Yeah, that's plenty of CPU speed. The GPU is more important for IL-2, are you talking GPU speed? Size of chache is very important next to speed of processing. However, software and internal instructions about a chip is another huge factor. This is why AMD and NVIDIA produce great IL-2 experience for less money. They really have their software support in the lead over Intel and ATI, though the later have faster clock speeds in their chips.
