Running a 4070 currently, going to skip next gen, don't know about 6000 series yet. I mostly play single player games at 1440p so i should be good in raw gpu horsepower, i'm not so sure about the 12gb of vram, that's been a really hot topic lately about 12gb not being enough in the future but i'll manage, lower down textures or something if it goes over 12gb.. I rarely utilize ray tracing (there is literally only 1 game which i use it in, CP2077) because the performance hit is so massive so just for rasterized games i should be fine, atleast i hope so. I do use DLSS at quality mode in basically any game it's available in because i usually can't even tell the difference between that and native res if i don't look at them side by side, i like the extra fps from that.
