The spec doesn't get me all that worked up. The 772MHz core, and 4,008MHz memory clock combined with 1,536MB of GDDR5 makes this more of a GF100 upgrade than anything else.
Oh, one more thing. And this does get me worked up, or more accurately, annoyed. That number, 4,799, that's ¥4,799CNY, which according to my calculator works out at around $720! That is a lot of dough! Even at $599 this card is going to face serious competition from AMD's 6800-series cards.
