You dont need too powerful GPU to run crysis 3 maxed, it's done on the same engine as Crysis 2 and console restrictions will hold it back. Unless they want to make PC version way superior in every way (more entities, larger maps, more visual effects, etc).
I would recommend getting a GTX 660ti or 7950 for now, and getting a new GPU in +3 years. (maybe +5 depending on next gen console specs). Those should be plenty good enough to run any game without any hitching for a looooong time.
just get an i5 CPU if u want to play Rome 2, that game most defo is gonna be a CPU hog. :)
Only PC game that actually needs horsepower is planetside 2 atm, and thats because it's a PC exclusive that pushes the hardware boundaries.
