A capture card takes an HDMI signal from a console or a second PC and hands it to your streaming machine as a video source. This guide focuses on the criteria that actually matter so you can pick the right card for your setup instead of overpaying for specs you'll never use.
Quick Answer
Match the card to your source: a USB 1080p60 external card covers most console and single-camera setups, while a PCIe 4K60 card only makes sense for 4K console capture or a dedicated dual-PC rig. Buy for the resolution and framerate you'll actually broadcast, not the highest number on the box.Do You Even Need a Capture Card?
You need one when the video you want to stream lives outside your streaming PC:
- Console streaming — PS5, Xbox Series X/S, or Nintendo Switch feeding your PC.
- Dual-PC setups — a dedicated gaming PC sends its output to a separate streaming PC. See our dual-PC streaming setup guide for the full workflow.
- Camera input — using a DSLR or mirrorless camera with a clean HDMI out as a high-quality webcam.
You do not need one if you're streaming PC games from the same PC you broadcast on. OBS Game Capture reads the frames directly with no capture hardware involved.
The Criteria That Actually Matter
Capture resolution and framerate
This is the number that defines the card. Cards are marketed by what they hand to your PC:
- 1080p60 — the sweet spot for the vast majority of streamers. Twitch caps non-partner bitrate around 6,000 Kbps, which is built for 1080p, so most viewers never see more than this anyway.
- 4K60 — worth it only if you genuinely broadcast or record in 4K, or want a high-quality local recording while streaming a downscaled version.
Don't confuse capture resolution with passthrough resolution (more on that below). A card can pass 4K to your monitor while only capturing 1080p to your PC.
Passthrough
Passthrough sends the source signal straight to a second monitor or TV with effectively zero added latency, so you play on a clean feed while the card captures a copy. Two things to check:
- Passthrough resolution/refresh — a good card passes through a higher spec than it captures (e.g. 4K120 or 4K144 passthrough while capturing 1080p60), so console players keep their high-refresh gaming experience.
- HDR and VRR — if you game in HDR or use variable refresh rate, confirm the card passes those through; many budget cards flatten HDR or drop VRR.
USB vs PCIe (external vs internal)
This is the biggest structural decision. See the table below, but the short version: USB (external) for flexibility and laptops, PCIe (internal) for the lowest latency in a fixed desktop dual-PC build.
Software and OBS compatibility
A card is only as good as its drivers. Well-known lines from Elgato and AVerMedia are popular largely because they show up cleanly as a Video Capture Device in OBS and Streamlabs with minimal fuss. Cheaper no-name cards can work but often need extra configuration or introduce audio-sync headaches. If you hit sync problems, our guide on how to fix audio sync issues in OBS covers the usual culprits.
Latency
All capture adds a little delay to the captured feed — which is exactly why passthrough exists (you play on the passthrough, not the captured image). PCIe cards generally add the least latency; USB 3.0 cards are close behind; older USB 2.0 cards add the most.
USB vs PCIe Capture Cards
| Factor | USB (External) | PCIe (Internal) |
| Installation | Plug and play | Open the case, seat the card |
| Portability | Move between PCs/laptops | Fixed to one desktop |
| Latency | Low (USB 3.0) to moderate (USB 2.0) | Lowest |
| Bandwidth headroom | Capped by the USB bus | High — good for 4K60 capture |
| Best for | Consoles, laptops, single-PC captures | Dedicated dual-PC and 4K rigs |
Card Categories by Use Case
Rather than chase specific model prices (which shift constantly), match your situation to a category:
- Budget 1080p console capture — a compact external USB card. Great for streaming a single console at 1080p60. Compact USB 2.0 options exist but add more latency than USB 3.0.
- Mainstream 1080p60 external — the workhorse category. A USB 3.0 external card with HDR passthrough handles PS5/Xbox/Switch and doubles as a camera capture. This is what most streamers should buy.
- 4K external — a USB 3.x card that captures 4K60 without opening your case. Good for creators who want 4K recordings but value portability.
- 4K internal (PCIe) — for dedicated dual-PC setups or 4K console capture where you want the lowest latency and highest bandwidth headroom. Look for high-refresh passthrough if you game above 60fps.
Both Elgato and AVerMedia field cards across all of these tiers, so pick the tier first and compare current models within it.
Setting Up a Capture Card in OBS
1. Connect your console or gaming PC to the capture card's input.
2. Connect the capture card to your streaming PC via USB or PCIe.
3. In OBS, add a Video Capture Device source.
4. Select the card from the device dropdown.
5. Set the resolution/FPS to match the card's capture output (usually 1080p60).
6. Configure your stream bitrate for that output.
Since a card outputs at a fixed resolution, your encoder settings are identical to normal streaming. Use the bandwidth calculator to confirm your upload can carry the bitrate, and the 1080p 60fps bitrate reference for target numbers. If your card captures 4K, check the 4K 60fps page and be sure your upload speed can sustain the much higher bitrate.
FAQ
Do I need a 4K capture card for a 1080p stream?
No. If you broadcast at 1080p, a 1080p60 card is the correct choice. A 4K card only helps if you capture or record in 4K locally.
Will a capture card add input lag to my gameplay?
Not if you use passthrough. You play on the passthrough output, which is essentially lag-free; only the copy sent to your PC carries the small capture delay.
USB or PCIe for a dual-PC setup?
Either works. PCIe gives the lowest latency and most bandwidth for a permanent desktop rig; a USB 3.0 card is fine and far easier to move or troubleshoot.
Bottom Line
Buy for the resolution you'll actually stream. Most creators are best served by a mainstream USB 3.0 1080p60 external card with HDR passthrough — well-supported lines from Elgato and AVerMedia are safe picks. Step up to a PCIe 4K60 card only for dedicated dual-PC builds or genuine 4K capture. Once your hardware is sorted, dial in your encoder with the bitrate tools and platform-specific settings for Twitch or YouTube.
