yea, that'll be fine, but why the phenom? either get one of the newer ones (which are only 95 tdp on full load) or get an intel one. the x4 is just not a good buy...what is your budget by the way. and what are you gonna use your build for? gaming?
That phenom is fine its the same or better then the fx 4300 and its low cost. Get an after market cooler like a hyper 212 and overclock it will perform fine.
