I had question, I tryed building the most expensive/highest end/most powerful alienware computer and tried the same thing with a dell XPS and in both of them, the best processor option you can get is a Core i7 965 Extreme, I thought this this was the highest end gaming processor currrently. However, the Core 2 Extreme Qx9775 costs wayyy more, like 400-500 bucks more and has higher clock speed????am i missing something?Anybody explain which one is better and why?
