It's doable i think two GTX 570 gpu's at lower frecuency, 600Mhz with lower voltage.
It should be 35-45% faster than GTX 580, but it would be faster than 6990? It depends on what 6970 is.
The 6990 seams to have gone back to drowning-board, and delayed to next year, just after they saw the GTX580, apparently.

The timing of GTX570 suggests that nVidia is preparing it to to compete with AMD's upcoming single-GPU (6980) too.

So yes, indeed, it will be interesting to see what comes out of the new-drown 6990, but these delays are suggesting that AMD is straggling. Nothing is clear yet thought, we have to wait and see.
