TLDR
If you bought a new 50 Series card, old games which have PhysX implementations for cool stuff in game will just grind to a halt and wont work.
25FPS vs 160FPS
66FPS vs 415FPS

You can run it on a CPU (but not in every game), that's literally what the test is comparing.
But the PhysX in those cases runs on a single thread and uses some old deprecated instructions so it runs like shit even on the best CPU today, probably a combination of Nvidia not bothering to update old legacy code they took over and trying to intentionally cripple AMD performance with PhysX.

yeah, but the reason it was originally implemented on GPU is because CPUs aren't good at that task.
