So I have Asrock 970 pro 3 and I need a new cpu to go with Sapphire Radeon HD 7950. Will the FX-6300 be okay? But actually I want to get fx-8320. It is on that mobos cpu support list but will it work great though? NOT planning on overclocking. Other specs: 620w PSU 8GB RAM (My cpu at this time amd phenom II x4 965be)
