Far Cry 2
The Dunia Engine was built specifically for Far Cry 2 by the award-winning Ubisoft Montreal development team. It delivers the most realistic destructible environments, amazing special effects such as dynamic fire propagation and storm effects, real-time night-and-day cycle, dynamic music system, non-scripted enemy A.I. and so much more.
Across the board we can see that the numbers are very similar between all the different setups. That's mainly because when it comes to games the most important thing you want is more MHz on the CPU, this after first getting a faster video card of course.
