I have a MSI 870A-G46 motherboard with an Athlon x3 on it currently. I have some questions about CPU upgrading without buying a new motherboard, with the am3 socket can I put this in it AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 125W Quad-Core Processor HDZ965FBGMBOX ? Or are there even better options for the money?
