I'm planning to buy a new computer, it will mainly be used for gaming.The question is like this: At first I was planning to buy an Intell 660 (3.6 Ghz) and a video card based on geforce 6800 GT. Now when the 7800 model came out I'm not sure what to do... Should I get the 7800 model and an Intell 650 (3.4 Ghz) or stick with my old plan, since they both fit in my price range.
