The 4K X is what you buy when you want zero compromises. HDMI 2.1 across the board, 4K144 HDR10 capture and passthrough, VRR support, and a single USB cable connection. PC Gamer calls it the best capture card overall for 2026. The only reason to look elsewhere is price — at $230, it's roughly double the Razer Ripsaw HD and 50% more than the Elgato HD60 X.
Strengths
- +HDMI 2.1 input and output with full 4K144 HDR10 passthrough and capture
- +VRR (Variable Refresh Rate) passthrough means PS5 and Xbox Series X games stay smooth
- +USB 3.2 Gen 2x2 single-cable connection — no separate power adapter required
- +OBS-friendly with rock-solid driverless install on Windows and Mac
- +PC Gamer and TechRadar consistently rank it the best capture card overall in 2026
Watch-outs
- −Most expensive pick in this round-up
- −Requires USB 3.2 Gen 2x2 (20 Gbps) for full 4K144 — older USB ports will downscale
- −4K144 capture files are huge — plan storage and bitrate accordingly
- −Overkill for streamers who only output 1080p60 to Twitch/YouTube
How it compares
Most capable card here on every axis — capture resolution, refresh rate, HDR, passthrough latency. The AVerMedia Live Gamer Ultra S matches 4K60 capture at a lower price but lacks the 4K144 ceiling. The Elgato HD60 X tops out at 1080p60 capture. PCIe-based AVerMedia Live Gamer 4K matches on capture spec but needs a desktop and a free PCIe slot.
Who this is for
At a glance: professional streamers and content creators who output 4K HDR or 4K120/144 and want HDMI 2.1 throughout.
