Mafia II GPU & CPU Performance In-depth
 

Mafia II is a third-person action shooter that combines Grand Theft Auto-like gameplay mechanics with a world heavily inspired by the classic films Godfather and Goodfellas. Developed by the same team as the original (2K Czech, formerly Illusion Softworks), Mafia II was released for the Windows platform last August 24th. The game also received simultaneous launches for the PS3 and Xbox 360, but in spite of this the visual quality of the PC version does not suffer from the "crappy console port" syndrome. Rather Mafia II looks to be one of the best games of 2010 to show off the capabilities of current generation high-end GPUs.

So with a new full version copy of Mafia II loaded onto our test system and two dozen graphics cards lined up ready to test, we set about to deliver another GPU & CPU performance article. Not only have we tested a huge range of graphics cards, but we will also look at the impact PhysX has on performance with and without a dedicated card. As usual, we'll also take a quick look at CPU scaling performance for those concerned if they have the necessary guts on that front as well.

large differences changing/upgrading CPUs, more than I would have expected!
