I am running quad screens and a Asus M4A78 plus with an AMD Athlon 64 X2 6000+ 3.0 ghz! Along with 2 invidia GeForce 9600gt bridged and I want to upgrade to the best CPU I can for this mother board, this MB has given me no problems and I want to learn how to upgrade the CPU anyways, but I am having problems understanding what CPU can be used or which one is the best. It says AM3 CPU support on the MB but I thought it was an AMD 2 socket. so does that mean I can run AM3? Don't laugh I wanting to learn. I like gaming and I do some web design with video editing/ graphics. I am not looking to switch out Everything to update to a more current set up, just want to upgrade CPU. Any help would be greatly appreciated, thank you in advance.
