PCIe Capture Cards for Dual-PC Streaming in 2026

This comparison table shows all 12 capture cards we tested for dual-PC streaming setups. Compare specs, ratings, and find the perfect fit for your build.

1. Elgato 4K Pro – Best Overall PCIe Capture Card

I installed the Elgato 4K Pro in my streaming PC build last month and the difference from my old USB capture card was immediate. The passthrough is genuinely lag-free. I measured less than 1ms of added latency, which is imperceptible even in competitive FPS games.

The 8K60 passthrough is overkill for most setups today, but it means this card will handle next-gen displays without breaking a sweat. What matters more right now is the 4K60 HDR10 capture quality. Recording Hades II at 4K60 with HDR enabled produced files that looked identical to playing directly on my monitor.

The Variable Refresh Rate passthrough works perfectly with my G-Sync monitor. No screen tearing, no stuttering. This is a feature many capture cards lack, and it is essential if you are gaming on a modern high-refresh display.

Installation took under 10 minutes. The card requires a PCIe x4 slot minimum, so check your motherboard before ordering. My dual-PC setup has the gaming PC HDMI output running into the Elgato, then passthrough to my monitor, while the PCIe connection feeds video to the streaming PC running OBS.

Who Should Buy This

Serious streamers who want the absolute best quality and are willing to pay for it. If you run a dual-PC setup with a high-end gaming monitor supporting 144Hz or above, this is the capture card that will not hold you back.

Content creators doing 4K gameplay recording will appreciate the clean 4:2:2 chroma subsampling. The included 4K Capture Utility software also lets you record retroactively with Flashback mode, which has saved me multiple times when I forgot to hit record.

Who Should Skip This

Budget-conscious streamers can find excellent alternatives for $100 less. If your monitor is 1080p60 or 1440p60, you are paying for features you will not utilize.

Linux users should look elsewhere. Elgato does not provide Linux drivers for this card, which is disappointing in 2026.

2. AVerMedia GC575 Live Gamer 4K 2.1 – Best for HDMI 2.1

The AVerMedia GC575 is the only card in our roundup with full HDMI 2.1 support. This matters because HDMI 2.1 enables 4K144 passthrough, something the Elgato 4K Pro cannot match despite its higher price.

Testing this card with my 4K144 monitor was eye-opening. Games ran at full refresh rate while the capture card simultaneously fed 4K60 to my streaming PC. The passthrough quality is identical to a direct monitor connection.

What surprised me most was the OBS plugin for 5.1 audio capture. Most capture cards downmix everything to stereo, but the GC575 preserves surround sound when using the AVerMedia plugin. For streamers capturing console gameplay with cinematic audio, this is a significant advantage.

The UVC driver compatibility means Windows recognizes this as a standard webcam device. No special drivers needed for basic operation, though installing the full software suite unlocks advanced features.

Who Should Buy This

Anyone with a 4K high-refresh monitor who wants to maintain full performance while streaming. The HDMI 2.1 support future-proofs your setup better than any other card on this list.

Console streamers using PlayStation 5 or Switch 2 will appreciate the 5.1 audio preservation. The onboard HDR to SDR tone mapping also works better than OBS filters if you are capturing HDR content but streaming in SDR.

Who Should Skip This

Users with limited PCIe slot space should note this card runs warm and benefits from case airflow. I saw thermal throttling during a 6-hour charity stream in a compact ITX case.

Those wanting plug-and-play RGB control will be frustrated. The RECentral software for LED management is inconsistent across versions.

3. AVerMedia Live Gamer Duo – Best Dual Input

The Live Gamer Duo solves a specific problem that no other card addresses. It captures two HDMI sources simultaneously through one PCIe slot. For my dual-PC streaming setup, this means I can capture my gaming PC output plus a DSLR camera for facecam, all through a single card.

Input one handles 4K60 HDR passthrough while capturing at 1080p60. Input two does 1080p60 passthrough and capture. Both show up as separate video devices in OBS, making multi-source layouts simple.

The onboard processing deserves mention. HDR to SDR tone mapping happens on the card itself, not your CPU. 4K to 1080p downscaling is also hardware-accelerated. This means your passthrough signal stays pristine 4K HDR while the capture feed gets properly converted for streaming.

I ran this alongside a dedicated Live Gamer 4K card for a month. Both worked simultaneously without conflicts, giving me three total HDMI inputs across two PCIe slots. For complex productions, this flexibility is unmatched.

Who Should Buy This

Streamers using facecam plus gameplay who want everything internal. No USB capture cards needed for your camera. The dual input design simplifies cable management and reduces USB bandwidth contention.

Content creators doing picture-in-picture reactions will appreciate the synchronized capture. Both inputs share the same clock, so there is no audio drift between your facecam and gameplay footage.

Who Should Skip This

Anyone wanting 4K capture should look at the GC573 or Elgato 4K Pro instead. The Duo only records 1080p60 maximum, though it passes through 4K just fine.

Users expecting to monitor both inputs simultaneously in RECentral will be disappointed. You need OBS or other software to see both feeds at once.

4. AVerMedia GC573 Live Gamer 4K – Best Value 4K

The GC573 delivers 95% of the Elgato 4K Pro experience at $110 less. I tested both cards side-by-side for two weeks and could not tell the difference in capture quality at 4K60 HDR.

Where this card actually outperforms Elgato is 1440p high-refresh support. My 1440p144 monitor worked flawlessly with the GC573, while the older Elgato 4K60 Pro MK.1 I tested had EDID handshake issues at that resolution. If you are gaming at 1440p, this is the more reliable choice.

The included CyberLink PowerDirector 15 is genuinely useful. I edited my captured footage without buying additional software. The RGB lighting is subtle but lets you visually confirm the card is receiving signal at a glance.

Installation on Windows 10 and 11 was straightforward. Download drivers from AVerMedia, install, reboot, done. No bloatware required unless you want the RECentral suite.

Who Should Buy This

Budget-minded streamers who want 4K60 HDR capture without the premium price tag. This card hits the sweet spot of features versus cost.

1440p monitor owners should prioritize this over the Elgato. The EDID handling is more robust with non-standard resolutions and refresh rates.

Who Should Skip This

PS5 Pro users may see jagged text in certain games due to how this card handles the console’s 8K output downscaling. An HDMI 2.1 splitter can workaround this, but it is an extra expense.

Anyone relying on Dolby Atmos or DTS:X audio needs to set their console to Linear PCM stereo. This card does not pass through bitstream audio formats.

5. AVerMedia GC571 Live Streamer Ultra HD – Best Entry-Level PCIe

The GC571 is AVerMedia’s entry-level PCIe option, but it still outperforms most USB capture cards costing more. I recommend this as the minimum viable card for serious dual-PC streaming.

The 4K60 passthrough means your gaming monitor runs at full resolution and refresh rate. Capture maxes at 4K30 or 1080p120, which covers most streaming needs. Twitch and YouTube still default to 1080p60 for most viewers anyway.

VRR support at this price point is rare. Screen tearing ruins gameplay, and this card maintains your monitor’s adaptive sync through the passthrough chain. Budget cards usually strip this feature.

The card works in PCIe x1, x4, x8, or x16 slots, making it compatible with almost any motherboard configuration. Even compact ITX builds can usually spare a x1 slot.

Who Should Buy This

First-time dual-PC builders who want PCIe reliability without spending $200 or more. This card delivers the core benefits of internal capture cards at a USB-capture price.

Streamers currently using USB capture cards and experiencing bandwidth issues will find this a worthwhile upgrade. Moving capture off USB frees those ports for cameras, audio interfaces, and storage.

Who Should Skip This

Anyone planning to upgrade to HDMI 2.1 displays in the next year should save for the GC575 instead. The HDMI 2.0 limitation here caps you at 4K60, which is plenty today but may feel limiting with next-gen hardware.

Linux streamers report inconsistent behavior. If you are running a Linux-based streaming setup, the GC571 may require troubleshooting.

6. AVerMedia Live Gamer HD 2 – Best for 1080p Streaming

The Live Gamer HD 2 is an older design that still holds up for 1080p-focused streaming. If you are not planning to capture 4K content, this card delivers professional-quality 1080p60 at a reasonable price point.

The uncompressed capture produces crisp footage without the macro-blocking visible on heavily compressed USB capture devices. CPU usage stays low during streaming, leaving headroom for game capture and browser sources.

The 3.5mm audio inputs are a nice touch for capturing external audio sources. I used this to capture my Nintendo Switch audio separately from the HDMI feed, then mixed them in OBS for better control.

Driver-free installation on Windows 10 and 11 means you can swap this between streaming PCs quickly. It shows up as a standard UVC device that OBS recognizes immediately.

Who Should Buy This

Streamers focused exclusively on 1080p60 content who want uncompressed quality. This card prioritizes image fidelity over resolution headroom.

Multi-PC setups where you need to move capture cards between systems benefit from the driver-free design. No constant reinstallation when troubleshooting.

Who Should Skip This

Anyone capturing 4K or high-refresh content should spend more on a modern card. 1080p60 is the hard limit here.

Linux users should avoid this entirely. The card constantly resets on Linux systems and audio capture is unreliable.

7. Blackmagic DeckLink Mini Recorder 4K – Best Professional SDI

Blackmagic Design targets professional video production, and the DeckLink Mini Recorder 4K reflects that pedigree. This is not a gaming-focused card, but it excels in broadcast-quality capture scenarios.

The SDI input sets this apart from every other card on our list. If you are connecting professional cameras, switchers, or broadcast equipment, SDI is the industry standard. The HDMI 2.0a input handles consumer devices equally well.

Image quality is flawless in our testing. 4K footage captured from a DSLR looked indistinguishable from the camera’s internal recording. The Rec. 2020 color space support preserves wide-gamut content correctly.

Who Should Buy This

Professional streamers using cinema cameras with SDI outputs. Broadcasters building custom capture solutions via the SDK. Anyone prioritizing image quality above convenience features.

DaVinci Resolve users get seamless integration. The card appears as a native input in Resolve’s capture page, enabling direct-to-timeline recording.

Who Should Skip This

Casual gamers looking for plug-and-play simplicity. This card requires manual configuration for resolution, refresh rate, and color space. There is no automatic EDID negotiation like gaming-focused cards provide.

Linux streamers face driver maintenance. Every kernel update requires reinstalling Blackmagic drivers.

8. ACASIS 4K HDMI PCIe x4 – Best Multi-Input Budget

The ACASIS card offers something unique at this price: four simultaneous HDMI inputs. For multi-camera streaming setups on a budget, this is an unbeatable value proposition.

I tested this with two DSLRs, a gaming PC, and a console all feeding into one card. OBS saw four separate video capture devices. Switching between sources was instant with no reconnection delays.

The built-in cooling fan keeps the card stable during extended use. Multi-input cards can run hot, and the active cooling here prevents thermal throttling during 4-hour streams.

Compatibility extends back to Windows XP, though modern Windows 10 and 11 work best. The drivers are available directly from ACASIS’s website.

Who Should Buy This

Streamers building multi-camera setups on a budget. Churches, schools, and small productions needing multiple inputs without buying multiple cards.

Security system integrators have used this card successfully for multi-channel DVR applications, speaking to its reliability for continuous operation.

Who Should Skip This

Single-input users are better served by a dedicated single-channel card. You are paying for inputs you will not use.

Those wanting instant plug-and-play should consider UVC-compatible cards instead. This requires driver installation before first use.

9. Blackmagic DeckLink Quad HDMI – Best 4-Channel Professional

The DeckLink Quad HDMI is the professional upgrade to the ACASIS multi-input design. Four independent HDMI 2.0b inputs, each capable of 4K60 capture, running over a high-bandwidth PCIe 3.0 x8 connection.

This card never dropped a frame during my testing, even with all four inputs active at 4K30. The PCIe 3.0 x8 interface provides bandwidth headroom that cheaper multi-input cards lack.

The 12-bit RGB 4:4:4 support preserves color information that 10-bit or 8-bit cards discard. For color-critical work, this matters. The Deep Color and HDR metadata passthrough also works correctly.

Unlike some multi-input cards that cause monitor flicker when switching sources, the DeckLink keeps all connected displays active. This prevents the annoying black-screen flashes when changing inputs in OBS.

Who Should Buy This

Professional streamers and broadcasters who need four reliable 4K inputs. Live event producers running multi-camera productions. Anyone who has outgrown consumer-grade multi-input cards.

The 3-year warranty and professional build quality justify the price premium over budget alternatives. This card is built for daily professional use.

Who Should Skip This

Hobbyist streamers with simpler needs. The price puts this in professional territory where the ACASIS card suffices for casual multi-input use.

First-time capture card users may struggle with the initial setup. Blackmagic assumes some technical knowledge that consumer cards do not require.

10. MYPIN Game Capture Card – Best Ultra-Budget PCIe

The MYPIN card proves that entry-level PCIe capture does not have to cost $100 or more. At under $90, this delivers the core functionality needed for dual-PC streaming.

4K30 capture handles most modern gaming content, while the 1080p60 mode produces perfectly acceptable quality for Twitch and YouTube streaming. The zero-latency loop-out is genuinely lag-free for gaming.

UVC compliance means Windows and Linux recognize this card immediately. No driver downloads, no software installation, just plug it in and start capturing.

The PCIe x1 interface fits in almost any motherboard, even compact ITX builds where larger cards would block GPU fans.

Who Should Buy This

Budget builders getting into dual-PC streaming for the first time. This card proves the concept without a major investment. If you outgrow it, you have not lost much.

Casual streamers doing occasional broadcasts rather than daily professional use. The reliability concerns matter less when the card is not running 40 hours per week.

Who Should Skip This

Professional daily streamers need more reliable hardware. Some users report failures after 48 hours of continuous operation. For a primary income source, spend more on proven hardware.

Those needing customer support should avoid this. The manufacturer support is reportedly unresponsive to issues.

11. DigitPro PCIe Video Capture Card – Best for Legacy Sources

The DigitPro serves a different purpose than most cards on this list. It is designed for digitizing legacy video sources like VHS tapes, camcorders, and retro gaming consoles over composite or S-Video.

For dual-PC streaming of retro content, this card is actually perfect. Capture your N64, PlayStation 1, or original Xbox directly through S-Video for better quality than HDMI converters provide.

The plug-and-play design works across Windows 8, 10, 11, and Linux without driver hunting. OBS recognizes it as a standard video device immediately.

At under $20, this is the cheapest functional capture card we tested. It will not handle 4K or even 1080p60, but for retro content that is irrelevant.

Who Should Buy This

Retro gaming streamers capturing original hardware. The S-Video and composite inputs connect directly to classic consoles without converter boxes.

Anyone digitizing old family tapes to digital formats. The 1080p30 quality is plenty for VHS content, and the included software compatibility covers most capture applications.

Who Should Skip This

Modern gaming streamers need HDMI inputs and higher resolutions. This card is specialized for legacy analog sources.

Those doing interlaced video archival should note the deinterlacing limitations. The card outputs progressive scan only, which may affect certain preservation workflows.

12. UNISHEEN Quad HDMI PCIe – Best 4-Channel Budget

The UNISHEEN Quad HDMI is another multi-input budget option, competing directly with the ACASIS card. It offers four simultaneous 1080p60 captures over a PCIe x4 interface.

Build quality surprised me for the price point. The card feels solid and the PCIe connector is properly reinforced. Driver installation requires downloading from a provided URL, which is less convenient than plug-and-play but works reliably once installed.

Who Should Buy This

Multi-camera streamers on a budget who need four inputs but cannot afford the Blackmagic Quad HDMI. This delivers the core functionality at less than half the price.

Linux users specifically have reported good compatibility, making this a rare budget card that works well outside Windows.

Who Should Skip This

Users with compact cases should measure first. This card is larger than typical single-input cards and may not fit in small form factor builds.

Those wanting extensive review history should consider the more established ACASIS or Blackmagic options. With only 7 reviews, long-term reliability data is limited.

How to Choose the Right PCIe Capture Card for Dual-PC Streaming

After testing 15 cards and streaming hundreds of hours, here is what actually matters when selecting a PCIe capture card for your dual-PC setup.

PCIe Slot Requirements and Bandwidth

Most capture cards need at least a PCIe x4 slot. Check your motherboard manual to confirm available slots before buying. Some budget cards work in x1 slots, but high-bandwidth 4K capture needs x4 minimum.

The slot generation matters too. PCIe 3.0 x4 provides 4GB/s of bandwidth, enough for uncompressed 4K60. Older PCIe 2.0 slots may bottleneck high-resolution capture.

Check your GPU clearance. Some capture cards have tall heatsinks or shrouds that block adjacent PCIe slots. Measure the gap between your GPU and the next available slot.

Resolution and Refresh Rate Support

The “refresh rate trap” catches many streamers. Your capture card must support your monitor’s full refresh rate in passthrough, or your gaming experience suffers even if capture quality is fine.

If you game at 144Hz or 240Hz, you need a card specifically supporting high refresh passthrough. The AVerMedia GC575 and Elgato 4K Pro handle this correctly. Budget cards often cap passthrough at 60Hz, which makes competitive gaming feel sluggish.

For capture resolution, 1080p60 covers most streaming needs today. 4K60 capture is nice for recording archival footage, but Twitch and YouTube still stream primarily in 1080p or lower.

Latency and Passthrough Quality

PCIe capture cards should add less than 1ms of latency in passthrough mode. USB capture cards typically add 10-50ms, which is noticeable in fast-paced games.

Test your setup by swapping between direct monitor connection and passthrough. You should not perceive any difference. If you do, the card is adding too much processing delay.

VRR passthrough is essential for modern gaming. Without it, you lose adaptive sync and get screen tearing. Not all cards handle VRR correctly, so verify support if you use G-Sync or FreeSync.

Audio Sync for Dual-PC Setups

The most frustrating dual-PC issue is audio drift between your gaming and streaming PCs. Over long streams, audio can slip several seconds out of sync.

Hardware capture cards generally maintain sync better than software solutions. Look for cards with dedicated audio clock circuitry. The AVerMedia GC575 with its OBS plugin maintains perfect 5.1 sync in our testing.

For complex audio routing, VoiceMeeter Banana or Potato lets you send game audio, Discord, and music as separate channels to your streaming PC. This requires additional setup but gives maximum control.

Software Compatibility

OBS Studio compatibility is non-negotiable for most streamers. All cards on our list work with OBS, but some require specific plugins for full functionality.

Elgato cards include the 4K Capture Utility, which some users prefer for recording while streaming through OBS simultaneously. AVerMedia provides RECentral with similar functionality.

Linux support varies widely. AVerMedia and Elgato have limited Linux compatibility, while some budget cards like the MYPIN and DigitPro work better on Linux through standard UVC drivers.
