yeah the ATI does seem to be better, but if you look back at last generation everyone thought the same thing and it turned out to be opposite....the specs for the G70 have changed again and again, so I'd waint until around the first week of august and see some benches and real world gameplay before you make a decision unless you simply like ATI and that's the end of the story....
I prefer Nvidia, but even still I would personally wait to see which card does better and if it's ATI it's ATI, if it's not it's not......either way I wouldn't go by specs just yet because as of right now it's all been speculation and I'd sincerely hope nvidia wouldn't release a crappy card barely above the 6800Ultra standard to keep up with the ATI card soon to be released.
