Even though cyrsis outstrips any console game, it's only one game and is not representative of pc games in general.
My guess is that 'alot' of multiplatform games (pc/360/ps3) look best on the PC already. Though it's entirely subjective whether you think that difference is 'small' or 'large'.
I really don't see that much of a difference between pc games and consoles games in general (at the moment). Not until it is a common occurence that PC games outstrip console games even on their medium settings will I concede that pc games have taken over console games.
