It gets worse.
Those benchmarks were ran without antialiasing or anisotropic filtering.
Here are some more:

These are some stunningly low numbers for no AA and AF.
From
this page of the article:
"We ran all cards at 1024x768, and the highest end cards at 1280x1024. We also used the best possible shader setting for the hardware, meaning that the R3x0 hardware used the DX9 code path, the 5900 Ultra used the NV3x code path and everything else used the DX8.x code path.
All tests were run without Anti-Aliasing or Anisotropic Filtering enabled. Anti-Aliasing was not properly supported in this demo and thus wouldn't be representative of final game play."
This game is going to
chug.
