If PS3 is your main use- then you don't need a super duper video card. I would however go with at least a 3850 due to the fact that PS CS3 started a trend that will continue in that some filters are going to start using the GPU to offload from the CPU.
8GB of RAM- good thing to have for PS3.
Do you really need dual LAN connectors? If not you don't really need this board- get the P5E instead and save some money.
What kind of PSU are you running? You don't really need DDR2-1066 RAM either. DDR2-800 is fine unless you are trying to overclock the hell out of this thing.
