I agree that Combat flight sims have always required high end systems to get the best out of them. I did avoid buying two video cards and went with one very high end card with the possiblility of adding another if SLI performance made it worth while. So far it appears that hasn't been the case, although a few people I respect say SLI has given some extra performance.

I also recommend having a seperate SSD drive with only a copy of Windows7 64bit , COD, and its peripherials running on it. Your motherboard will give you the option to boot to two or more Windows copy's. I've never seen a decent combat flight sim yet that ran well with minimul spec machines.
