Rsector, it would be great if you gave us your budget.
As profoundnoah has mentioned gaming revolves around the GPU and not really the CPU (although depends on games) I do not mind his build apart from 2 things, the Mobo being A320 is very limited. Also I am not a fan of PSU's under 550W because they stop expandability.
Now with your new build, the change of the motherboard I do think is good. I still recommend the 550W, but as stated in the first line, you never gave anyone a budget of money to spend... so everyone is trying to keep it around the 850$ mark and now you are up to 950$...
