You can't expect linear performance increases across the board compared to the 5970. They are two completely different cards both with some pros and cons. For the most part crossfire 6870s seem to have better scaling. But I am sure there are some applications that will prefer 5870/5970 (because of the higher amount of stream processors maybe?). This type of performance isn't exclusive to this series of cards. I seem to remember strange gains and losses with the 8800 GTX vs 8800 GT/9800 GTX/etc. Changing the architecture, no matter how slight, ends up making a very different playing field.
