I have planing to build a gaming desktop which I have chosen AMD Phenom II x2 555BE. I have read many articles of how to improve the performance of the CPU, and I am not sure which is the best performance improvement to be done. Shell I overclocking the CPU to 4Ghz or overclocking the CPU to 3.8Ghz with cores unlock? I know that cores unlocking only supported with some botherboard with ACC function build in. I want to know the different in performance between these 2 treaks. Could anyone suggest what I should do please. Many thanks!
