Well unless you have no CPU at all, I'd hold off on the Phenom II X4 955 because that will just be $100 that you're throwing away. That board is made for a Bulldozer Zambezi CPU and that $100 would be much better spent towards getting that than an outdated Phenom II. As much as I love my Phenom II X4 940, I wouldn't buy another one at this stage in the game. I've ordered 16GB of DDR3 and I'm getting either an ASRock 990FX Extreme4 or an ECS A990FXM-A in anticipation of the FX-8150. Truth be told, the Phenom II is still a very fast and usable CPU, my PC still flies with it but I would only recommend it if you have nothing else. Then you could throw it on a cheap motherboard and use it in a backup system in case yours takes a dive.
