Only if you're streaming a console (PS5, Xbox, Switch) or a dedicated camera (DSLR/mirrorless) to your PC. A capture card takes the HDMI output and feeds it into your computer for OBS/Streamlabs. If you stream PC games directly, you don't need one — OBS captures the game natively. Capture cards are essential for console streaming and high-quality camera-as-webcam setups.
What capture resolution and passthrough do I need?
For 1080p60 streaming, an Elgato HD60 X (captures 1080p60 / 4K30, passes through 4K60) is the sweet spot. For 4K60 recording, you need a 4K60-capture card like the 4K60 Pro. 'Passthrough' lets you play on your TV at full quality while capturing at a lower resolution — important so a 1080p capture card doesn't cap your gaming display to 1080p.
Internal vs external capture card?
External cards (USB, like the HD60 X) are plug-and-play, portable, and work with laptops — the right choice for most streamers. Internal cards (PCIe, like the 4K60 Pro) offer the lowest latency and highest sustained capture rates for 4K60, but require a desktop with a free PCIe slot. Choose external for flexibility, internal for maximum 4K performance.
What is the best capture card for streaming PS5 and Xbox Series X?
The Elgato HD60 X ($150) is the most-recommended capture card for console streaming — it captures 1080p60 and 4K30, passes through 4K60 HDR so you play at full quality while recording at 1080p, and is USB-powered for any laptop or desktop. For 4K60 recording of console footage, the AVerMedia Live Gamer Portable 2 Plus ($100) and Elgato 4K60 Pro Mk.2 ($200, internal PCIe) are the alternatives. Most streamers don't need to capture above 1080p60.
Does a capture card affect gaming performance on my PC?
An external USB capture card adds minimal CPU load (2–5% on a modern CPU) for encoding the incoming video stream. An internal PCIe capture card is even lower-overhead since it bypasses the USB controller. The more significant factor is your streaming encoder — software encoding in OBS uses 5–20% CPU; hardware encoding via NVIDIA NVENC uses <1% CPU with negligible performance impact. The capture card itself is not the bottleneck.
Can I use a capture card to record a Nintendo Switch?
Yes, via the Nintendo Switch dock's HDMI output. The Switch outputs 1080p30 or 1080p60 depending on the game. Any USB capture card with HDMI input (Elgato HD60 X, AVerMedia Live Gamer Mini) captures Switch footage without additional software beyond OBS. Note: the Switch Lite has no HDMI output — capture only works with the standard Switch or Switch OLED in docked mode.
