Hello, I am about to buy a new Intel Quad Q6600 PC with ATI HD 4870 video card but before deciding to buy I wish to know how long would the Quad processors continue to support the coming PC games. As you know the Intel Core i7 (Nehalem) processors are due by the year's end do you think I would be able to play the future PC games with my Quad when the Intel Core i7 would be released? Also which Quad should go for, Q6600, Q9550 or Q9400? I mean which is the best in performance and is the most mainstream. Kindly inform. Thanks
