I have a friend that has that same board as well and he's runing at 955be oc'd to 3.8ghz, If planning to keep the board why jump from a X3 to a X4 black edition he's about to jump from a Phenom II X4 955 to a Phenom II X6 1090T. It only makes sense to jump forward than stay even or barkward. But. I don't know the rest of your setup either memory,cooling etc and the F10C bios started with the Phenom II X4 970 and above to the Phenom II X6 1090T remember that's a AM2+ motherboard. I would get a Black Edition C3 chip if it was me
