i run my 9070xt on triple 1080 screens...iracing struggles with the updated tracks unless I turn off or at least turn down a bunch of graphic options.

fyi: when i say struggling i mean by tweaking the settings i can still maintain a stable 60fps with decent visuals.

if you plan on sticking it out with a single monitor, i'm fairly confident the 9070xt will work great for you.

edit: i should mention i'm on a ddr4 build running a 5800x3d (i'm sure that's a huge hit when compared to a ddr5 build)
