I am going to buy a 6800 ultra and have searched the many sights on the internet about this card. Seems Evga and BFG are both good companies. I like the idea of BFG having an OC 6800 out of the box at 425. Is the evga at 400? What are your thoughts or should I look elsewhere like PNY etc....Before I make this purchase would like some feedback. Also my Alienware system had a 420 power supply and I purchased today a Antec True 550 Power supply from Zipzoomfly. Will this be sufficient? Thanks Scott
