I ran the benchmark on my Core 2 Duo with 945GM (mesa 7.0.1):

Open Arena:
 - 640x480:  840 frames, 9.5 seconds: 88.7 fps
 - 1024x768: 840 frames, 15.3 seconds: 55.0 fps

Quake 3:
 - 640x480:  1260 frames, 9.3 seconds: 135.4 fps
 - 1024x768: 1260 frames, 15.9 seconds: 79.4 fps

Note that I have the INTEL_BATCH environment variable set.
