I am designing a new PC and I need to know which one is better for gaming - the i5 650 or i5 750. The 750 has quad cores and an L2 8MB cache while the 650 has 3.2GHz with 8MB cache, but only two cores instead of four. I am trying to figure out which is best for gaming. To future proof the system I am leaning towards the 750, but for present day gaming the 650 would be greatly sufficient. I can always just spend $400 on a new CPU in a few years. Anyway, I just want to hear your opinions.
