Verdict

AVerMedia Live Gamer 4K

6 / 10 Expert Rating

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.

Elgato 4K X

9 / 10 Expert Rating

The right step up for creators who need genuine high-frame-rate 4K SDR capture (4K144/4K120) and VRR handling — provided you have a desktop with an open PCIe x4 slot, and you accept the 4K60 ceiling when capturing in HDR.
