I'm looking for a game (single player / multi / MMO / whatever) game that basically is the current generation's version of 'DOOM 3' (ie DOOM 3 could not be run at max settings using then-best-hardware)

I've checked out metro 2033 and it's pretty awesome, but my video card handled it fine. I have a (1) GTX480 btw.

If it's FF14 ... I'd rather it not be that.
