I would go with a 4 core or 6 core if your going to spend a little more. Must of the new game run better with 3 or more core. I updated to a 6 core AMD a month ago I'm still using a GTX 275 and it runs Black ops at Max setting at around 100 FPS. My old 2 core, I had everything on low and still was getting 50 FPS or less.
