Fingolfen, Re: "Looks like a software issue"
The author doesn't mention which benchmark he is talking about, but it very well could be Viewperf, the OpenGL benchmark. Tech Report experienced an issue with this benchmark that only affected the 2.0GHz Pentium 4 with the 12.41 nVidia drivers. After discussing the failure with nVidia and Intel, they found that the driver was at fault, and the 12.61 driver fixes the problem. It could be related.

"In the Awadvs, DX, and Light tests, the 2GHz P4 system shows some performance anomalies, turning in much lower scores than one would expect. I checked and double-checked this one. Vsync was disabled, the screen resolution and bit depth were set right, the proper drivers and patches were installed, the AGP aperture size was the same (256MB) as the other systems—everything seemed right. We checked with Intel, who in turn checked with NVIDIA. NVIDIA confirmed there is an issue with the 2GHz Pentium 4 and the current drivers. It apparently relates specifically to high graphics bandwidth benchmarks, and like us, they've only seen the problem in viewperf.
Newer (currently unreleased) drivers from NVIDIA, labeled version 14.61, resolved the problem for us. As you can see, the red bar on the graph (which represents results at 2GHz with the 14.61 drivers) shows the P4 2GHz performing more line with expectations."
