Who each one is for
it is not the pick for HDMI 2.1 features like VRR passthrough, get the GC575 instead and laptop users, this is an internal desktop-only PCIe card. The same goes for budget buyers who can find this discounted now that GC575 has replaced it. It is not the one for HDR console capture, this card doesn't support HDR metadata at all. Buy the MiraBox HSV321 4K Capture Card for budget streamers wanting 4K passthrough without an established-brand price and casual console capture where 1080p60 recording covers the need, though it is not built for buyers prioritizing established brand support and consistent firmware updates and HDR capture or passthrough, not supported on this card. It also earns its place with buyers who'd rather run OBS directly than a bundled proprietary app. Our rating of the AVerMedia Live Gamer 4K (6/10): still a capable 4K PCIe capture card if you can find it cheap and don't need HDR, otherwise the GC575 replaced it for good reason. Our rating of the MiraBox HSV321 4K Capture Card (5/10): genuinely competitive spec for the price, with the build and software consistency trade-offs typical of budget capture brands.
