Most of my capture work is retro — analog signals, unusual sync, cards that need real troubleshooting to get right. The GC573 is the opposite of that: a modern HDMI capture card that’s just supposed to work, and does.
What it is
The GC573 is an internal PCIe card for capturing HDMI sources: 4K60 with HDR10, and high-frame-rate modes up to 1440p144 or 1080p240. It connects over PCIe x4 rather than USB, and passes signal through with no added lag, so a display can stay connected downstream of it.
Specifications
- Interface: PCIe x4
- Capture: up to 4K60 with HDR10
- Passthrough: 2160p60 HDR / 1440p144 / 1080p240
- Recording bitrate: 150–240 Mbps
Where it fits
This is the card I reach for when the source is modern — a current console, a PC, anything HDMI-first — rather than the Micomsoft SC-512N1-L/DVI I use for older analog and retro-console capture. The two do different jobs: the Micomsoft earns its keep on awkward analog and sync edge cases, and the GC573 is what I use when I just want a clean, dependable HDMI capture without a fight.
Pros
- reliable 4K60 HDR capture with no added passthrough lag
- handles high-frame-rate 1440p/1080p sources well
- internal PCIe card — no USB bandwidth or driver quirks to fight
Cons
- HDMI-only — no help with analog or older retro sources
- needs a free PCIe slot, unlike a USB capture box
