Antilles 6990
Cayman XT 6970
Cayman PRO 6950
Barts XT 6870
Barts PRO 6850

Barts = midrange
Cayman = Flagship
Antilles = dual flagship


And Barts is supposed to be about as fast as HD5870? Great AMD.
The 6770 equivalent for the 6 series will be as fast as the 5870 from last gen. What's not to like? Should wait to see what the pricing is like first at least.
