Capture cards let you record and stream console gameplay to PC.
Resolution
1080p60 is standard for streaming. 4K passthrough matters if you game in 4K while recording at 1080p.
Low Latency
Pass-through lets you play with zero lag while the PC records.
Picks
Elgato HD60 X for streamers, AVerMedia for budget, and Razer Ripsaw for compact setups.
