none. think about what your gooing to get. all the am3+ boards are just old phemon2 boards thats been made to work with the am3+ an old board with nothing new to show for it. just one revision after another and a list of bios up dates per revision in the hopes to keep am3+ afloat i bought when it first came out and the talk was there was to be a new board with a new chipset[1090fx] with pci-e3 and what ever well that was droped and there still conning you into an old out dated board that leaves you in the past. its like if you got an old junkey 5 year old car and you put a new motor in it in the end you still got an old 5 year old junkey car. amd is into the fm chips not here anymore look over the a88x boards specs. and compair. then wait and see what the release of fm2+ will be. . am3+ is a dead end in my book.
