People seriously under estimate the benifits of a decent power supply. I payed alot of money for my 350w true power supply but it runs "that" 6800 card that Dan was talking about and his 340w power supply wouldnt. when i checked the specs of the 2 power supplys the more expensive one provided a 12A boost at the same voltage ranges on the power supplys.
So you get what you pay for IMO
