I'm able to get 1440p/60fps on new games with around medium settings and I'm still running a 1600X and 1080ti. Overpayed big time during that mining craze but got most back by selling my old pair of R9 290X cards which were highly sought after by miners.
1080Ti is a bit of an old girl at this point but still going strong. No Ray tracing/DLSS though which would have been really nice with Cyberpunk. Holding out for the next series I think.
1080ti is a beast for last last gen.
Only flaw as you've mentioned is ray tracing, and possibly DLSS, which is a must for 1440p/4k gaming.
If you're not too fussed about RT, then yes, hold out for the next gen 40xx series. No doubt the miners will balls up that launch too!
However, Cyberpunk with DLSS and RT is a joy to behold.
Not sure what the red team will offer in terms of their entry level card and how that'll compare. Never been a big ran of AMD GPU's though. Read horror stories regarding their drivers. Team green for me!
Do love AMD cpu's though.
