If a guy added a cheap 500w psu and vid card it wouldn't be that bad of a gamer. You won't be able to overclock it with that mobo, but not everyone is into that anyways.
Ok, that board will over clock. That's the bargain on that site right there. You get that barebones kit, the psu, and add a vid card to it like...a gts 250 and your good to go.
