4k works great when combined with FSR. On a 9070 GPU the frametime cost of FSR 4 is around 2 msec so you can just render the game at 1080P, upscale to 4k.
I usually play like this, it gives a very sharp image at 120-180W with a barely audible fan.

If you haven't tried machine learning based upscalers do give it a try! The newest generation (DLSS 4.5/FSR 4.1) are in general preferred by users over a native image since they provide a far superior way of native AA.
AI based frame-gen is also very good. 4k/120 Hz (1080p/60 FPS rendered) is very doable on mid-range cards these days.
