Bad news.

Rumor has it the 7990 won't be released now until late August. Also, instead of using 2 of the the new and improved XT2 GPU chips, it'll just use 2 regular Tahiti XT chips.

And to make things more interesting (confusing), it may also require 4 6-pin plugs instead of using 8-pins. Also, the 12GB version may no longer be made.
