Quadro-Scores
I also tried NVIDIA's Quadro, to see how the SPECviewperf scores look with this high-end OpenGL-card. Quadro is also using NVIDIA's GeForce-chip, but it comes with 64 instead of 32 MB of onboard memory.
The results are of course higher than the GeForce-results and Athlon still remains ahead of Coppermine.
