Same setup and same result. 5800X3D is a good match for a 4090. And the two are very power efficient per fps. So if you want to keep the heat down at a certain target fps at 4k, then you can’t do much better than this combo assuming you require a 4090s power to begin with.
Depends on your resolution/refresh rate target. I have 5800x3d and 4090 with LG C2 (4k/120hz), and I am pretty much never CPU bottlenecked.
