I have the same CPU OP... with my 1080Ti I can play anything at 1440p.
If I was you get a 3070 or 3060Ti, the DLS feature will do wonders for future proofing
Don't bother upgrading your cpu and ram unless you want to game at higher resolutions, they are fine for 1440p.
Huh? Higher resolution (say 4k) pushes the bottleneck towards the GPU, not the CPU. That’s where an older CPU is actually OK. The lower resolutions are where it’s important to have a current-ish CPU to match the GPU. I reckon CPU bottlenecks is the most misunderstood part of PC building.
A 4790k will bottleneck a 3060 Ti in current CPU intensive games, if desiring 60+ fps. Look at the difference in games at lower resolutions here vs 4k (same gpu):
