I have a high refresh 4k monitor (and a high refresh 3440x1440 monitor) and a 2080 Ti, so when
@Cooper said that a 2080 Ti just about coped with 4k, I could say from experience that he was talking complete rubbish. So I did. You might note that
@Cooper has a RTX 2080 and not a 2080 Ti, so is speaking from a position of ignorance, not knowledge. Sure you can enable RTX and other GPU killers, but I'm happily playing Borderlands 3 with details mostly cranked at 4k (Volumetric Fog is dropped to medium) and getting over 60 fps. And it's not just me: look at the frame rates
@fantasticCG is getting.
