Whoa, this escalated quickly...
As far as the time-demos go, I believe that you can't compare AT's scores directly to DT's and say one or the other is wrong. I do believe though that one should expect similar results over a variety of benches while all using upstanding hardware.
IMO it's not that the the DT's score was a flawed representation of the time-demo they ran, just that whatever time-demo they ran was a misrepresentation of the game as a whole.
If they picked the most intense section of the game to bench, state that. Instead of presenting a vague, all-encompassing "Quake 4" bench, tell us that it was really just "Quake 4: [insert chapter or level name] section." Otherwise they're claiming that the average frame rate Quake 4 lets a Kentsfield/X1950XTX get using the least useful AA and resolution of 1600x1200 is a mere 34 fps.
For instance, in Oblivion benches we don't care what the dungeon frames are because 99% of the time they're around 60 or higher. That's why when you see relevant Oblivion benches, they're segregated into "Outdoor", "Foliage", or "Oblivion Gate" sections.
While I certainly wouldn't have made a thread about it, I don't see the crime in questioning two sites different benches when the results are in such opposition to eachother. Afterall, this was just a preview and I do think it's safe to say that whatever time-demo made the X1950XTX get it's 34fps average, the 8800GTX underwent the same torture and did quite well.
I'm not going to get my underwear in a twist about whose benches were better and what not. I know how Quake 4 plays and what it takes to play it well. The point of the preview was to show just what realm of frames to expect from G80, and it accomplished that. It was never designed to show what realm of frames to expect from the X1950XTX since there are a great many different benches that do that while being more detailed.
G80 is 3 days away, it's already been demonstrated that it has the frames, I just hope that nVidia didn't throw IQ out of the window for its still very dominant DX9 userbase.
