This is just for the people who dont know much about Athlon 64's, not a guide though. For those of you who dont know, all Athlon 64's except the FX's are made on the same assembly line. So basically they are Athlon 64 ####. They are then tested at the set perfromance level of the 2800, 3000, and so on. Once the max stable level is met by a processor they are kept there and marketed at that level. The FX's are made seperatly then the other 64's, but are tested the same way. Not really that helpful, but its just something to think about when Overclocking, they are all the same.
