AVerMedia Live Gamer 4K (GC573)
1 source$139.99as of Oct 20

The AVerMedia Live Gamer 4K (GC573) is the internal-card pick, delivering 4K60 HDR10 capture and high-frame-rate 1440p144/1080p240 modes from a PCIe slot. Reviewers praise its low latency and superb footage, and it often undercuts Elgato's internal 4K60 Pro. The catch is a documented PCIe-bandwidth quirk that can cap capture near 55fps on some setups, so slot placement matters.

Strengths
  • — 4K60 HDR10 capture and passthrough as an internal PCIe card
  • — Supports high-frame-rate 1440p144 and 1080p240 capture
  • — Very low latency capture with playable preview window
Watch-outs
  • — PCIe x4 bandwidth quirk can cap capture near 55fps on some boards
  • — Requires an open PCIe slot, so no laptop or console-only use
AVerMedia Live Gamer Ultra S (GC553Pro)
Ranked #2 in Best Capture Cards for Streaming
AVerMedia Live Gamer Ultra S (GC553Pro)
3 sources$140as of Oct 20

The AVerMedia Live Gamer Ultra S (GC553Pro) is the value champion of the category, delivering 4K60 HDR capture with VRR plus 1440p144 and 1080p240 high-frame-rate modes at well under half the cost of the top Elgato. Reviewers found its 4K60 footage from a PS5 nearly indistinguishable from the pricier Elgato 4K X. The only real ceiling is the lack of HDMI 2.1, which most streamers will never miss.

Strengths
  • — 4K60 capture and passthrough with HDR and VRR support
  • — High-frame-rate modes: 1440p144 and 1080p240 capture
  • — Simple, reliable plug-and-play USB-C setup
Watch-outs
  • — No HDMI 2.1, so no 4K120 capture

How they stack up

AVerMedia Live Gamer 4K (GC573)

The GC573 is the only internal PCIe card here, capturing 4K60 like the AVerMedia Live Gamer Ultra S (GC553Pro) but inside the case.

AVerMedia Live Gamer Ultra S (GC553Pro)

The GC553Pro hits the 4K60 sweet spot for far less than the Elgato 4K X, which only matters if you capture above 4K60.
