I used to play in 1440p with a 1070ti and a i7-7700k, I'd get around 50-60fps in normal-high settings with some tweaks. BeamNG is more CPU dependent I think, so it will depend on what you have, but it'd work pretty well.
thanks because I am currently thinking about upgrading my 1080ti to a 4070 or rx 6800 xt because i like to put settings to the max and sometimes have stuttering
