If you already have 6800XT, why even ask? It's not like you can easily buy 3070 for a normal price anyway.It's a tough one my 6800xt will perform better in most of the games i play. Would i be missing out much by leaving RT off and running with the 6800XT?
6800XT should be fine for 1440p/60 with RT off. RT adds a significant tinge of photorealism - I love how it looks - but the game does look gorgeous without it too, just not quite as real.
I did a quick comparison
