10GB 3080 on a QHD 165hz monitor for me. The only game that I haven't been able to max out (other than RT which I never use) is Cyberpunk. I had to fiddle with a few sliders to keep it constantly above 60. VRAM has not been an issue for me yet.
I'll probably look at the 5080 eventually, but I don't even see any games on the horizon that are likely to push me into an upgrade. Maybe Judas?
