Every benchmark you review online shows the 6800 ultra out performs in every way. Every single magazine I've read says the same. He wanted to know which was best, I told him. I build and tech pc's everyday. I have as well seen both in action, and tested both. No comparison, 6800 wins. So yes, if you want the best, its a waste of money. If you like to pay top dollar for second best, then the ati is right up your alley.
