Dont get the q6600. I have one and I am now building a second system so it runs better. I run 5 accounts off the q6600 right now. It works but you have to put up with the low fps. If the Q6600 cost you 150.00 just get the i7 920 for 299.00. Much more room for the future. Then the ram you get will be DDR3. Get you a 4850x2 video card that can run up to 4 monitors if you wish for another 299 at newegg.com. The card beats nvidia 280's and almost does what the 4870x2 can do while costing a ton less. I would get a few 7200 drives and raid 0 if you are tight on money. If not you can go balls out and get a SSD for wow.. Thats really expensive. If you go DDR3 you will prob get 6gig or 12gig ram. They run in 3's instead of 2's like DDR2. Tomorrow I begin the hardware install for my new pc. Once its finished the plan is to run 2 accounts from the q6600 and 3 accounts from the i7 920.
