Think of how many FPS you get when running one of those demos, then imagine what if it was implemented in current game, which has other things to render, would you really get decent performance?
What we see in these demos might only be implemented fully in games in a couple of years, and by then we will have much more powerful cards, which will run those games only decently, using a single GPU.
This is how its always been.
Its just a technology demonstration. We're just finally starting to see some of the features that were shown in the 8800GTX tech demos 3 1/2 years ago.
