whatever you get, get 2 sticks of RAM otherwise you dual channel will not work properly, and will cause slightly slower preformance. Duo is the way to go, and this is coming from a hardcore AMD user. Trust me you wont regret it. ALSO: get aftermarket cooling for that Duo if you decide on that route. those things can get hot as **** if not kept in check. (the Zalman 9500 is a great air cooling choice. Water cooling can wait till you have more budget. IF you care about it that much)
