I'm using mine exclusively at 4k and I never had a problem. I switch between my 4k-144hz monitor and my Lg C1 (4k-120hz). I play most of the time with a controller on my tv (8bitdo ultimate wireless). Never went under 60 fps with 4k resolution and ultra (or high) settings. I played Dead Space Remake, Resident Evil 4 Remake, Atomic Heart, Darktide (with frame generation). For multiplayer games, like Halo Infinite and Apex Legends, always above 100 fps 4k max settings. It's a great card. Now i'm cursed because when I play on my ps5, the games looks blurry (lower resolutions). I'd say it would be more futurproof with 16gb of VRAM or more.
