If you play at native 4k at high end settings on pc
Then you will see the difference, and series x and ps5 will have incredible graphical fidelity at 4k
Series x with the extra gpu grunt and could grunt should push it further for third and first party
But fps wise, the difference between 30 fps and 60fps is night and day
So it depends what you want
Better graphics at 30 or 60 fps, or high framerate at lower resolution
Or the middle ground like what series x is doing on dirt 5, dynamic 4k at 120fps
