That would all depend on how much you are willing to spend. Any of the AM3/AM3+ boards will work fine for the Phenoms.
It also depends on whether you want dual graphics cards, overclocking features, or other features like 6GB/s SATA connections.
As for graphics, once again - how much do you want to spend? and what do you want to be able to play?
FPS game,starcraft,Heroes of Newerth,CallOfDuty 6,etc...
