i have processor quad core q9550 with acer mother board and 4 GB RAM..i am planing to buy nvidia 9800gx2 graphic card but i dont know the sufficient PSU for this card including my processor and board...plzz tell me the best PSU of sufficient watts and amp...
As for under performing I wouldn't say that it's not as fast as some of the later cards but it's a VERY respectable card.
I've had mine now for 2-3 years I think now great card only prob I had with it is it died on me yesterday I stripped it down and baked the PCB's and it's good as new again after new cooling paste and reassembly.
I'm a VERY heavy user and a avid 3d gamer and I can't say I've ever had any concerns with it's performance even in the heaviest 3d games.
Its a dual GPU card which has it's advantages depending on what you want to do with it.
Personally I have one with a 2kw PSU it never hurts to invest in a good quality PSU with stable voltages.
It may not be a 580 but then considering it's age its a brilliant card.
