Using a mouse, grab a window on your desktop and shake it around at 60HZ vs 90HZ. You can definitely see a huge difference. 90HZ looks far smoother.
About 500HZ - there's virtually no GPU that can push 500 FPS at 4K resolution for anything but the most trivial graphics.
Even high end GPUs struggle to push 120 FPS on modern games with ultra graphic settings.
