Not much. Raw power isn't the issue at the moment since most people can't suspersample to a res where they'll actually need it in the forseeable future. DESU after using a lot of headsets I think 2K per eye is more than enough for a while. What's going to be more important to squeeze performance and greatly improve perception is proper foveated rendering with eye tracking and a return to OLED panels and wider FOV's.
