GTA IV - Quad or Core i7 needed!

[Reznik Akime]

It seems many forget that the 360's CPU is of the multi-core PowerPC flavor and not x86. It's not that it's a bad port as much as it is what is lost when moving from PPC to x86.

Also, lets not forget that one core is mostly dedicated to lower level functions of the 360. You know, the in game dash and music player. The flashy stuff. This game really only has two clean cores to work with on the 360.
