i want to get the 6800 ultra but i dont know if my PSU can supply enough power for the card. i have an Antec truepower 430watt PSU..ive been hearing that the card needs at least a 480watt PSU and i wont buy the card cuz i just upgraded to this PSU and im not going to buy another one for a new videocard. i have doom 3 and so far its pretty badass. awesome graphics and ive been freaked out quite a bit now
