No, actually ATI has more raw power in GFlops. Unfortunately the architecture of the R600 (and in turn the RV670 which is a refresh of the R600) is such that it is extremley difficult to make drivers that keep the card working at peak efficiency.
One of the things I have pointed out repeatedly is the fact that though ATI Radeon cards boast insane numbers (GDDR4, a mess of stream processors, etc), the numbers mean nothing if the card's architecture is premature. If ATI would just freaking relax and focus on some more efficient architecture, maybe they could have a better chance of beating nVidia's flagships.
Keep in mind, not everyone can or will bother with putting together an SLI or Crossfire setup, so the main point is strong single cards, of which nVidia has been doing extremely well. ATI has better scaling, but seriously, the problems with crossfire or SLI, in my opinion, make it obvious that a multiple card solution isn't always the best, or cost-effective. A stronger PSU with the correct amount of cables, a crossfire or SLi motherboard, space requirements, and the rather unstable drivers associated with both Crossfire and SLI. Then there's the cost. You pay 2x as much for a 20% increase with SLI and a 50% increase with Crossfire, IF the video game is optimized for such.
Having a very strong single video card produced is important, and even though ATI's numbers would show that their video cards are superior, the architecture isn't as refined as nVidia's is, so nVidia can actually use less and still gain more.
