These numbers all sound weird to me.  I get 300 fps on an ancient Matrox G2=
00=20
on a system with a 700Mhz Athlon.  At work we typically get around 1600 fps=
=20
in glxgears with Radeon 8500's on systems with 865 chipsets and 2.4 - 2.8 g=
hz=20
P4s.  Sub-100 fps for glxgears seems slow even for software rendering.
