From what i have read people are getting on average 3.3 to 3.6 Oc on the aircooled Q6600 and 3.7 to 4.2 aircooled Oc on the e8400.Can you actually tell a difference in performance between those numbers in games or would you would be better off just getting the quad because of future programming in games to take advantage of multi core proc. as well as multitasking?The Quad being longer lasting down the road than the higher clock speed dual proc. as it were?
