Plus if you're like me, you like your PC producing the least heat possible (keep in mind the difference between that, and keeping your PC cool - two separate things) and it wins in that department as well.
Yeah, the 6850 would be a nice choice for him. Either way, he needs a new power supply as 300 watts is not near enough.
