I've never used glxgears before, so I decided to give it a whirl on my 
frontend.  I get *much* smaller numbers:

3057 frames in 5.0 seconds = 611.400 FPS
3172 frames in 5.0 seconds = 634.400 FPS
3162 frames in 5.0 seconds = 632.400 FPS
3173 frames in 5.0 seconds = 634.600 FPS

Of course, my system is very different from yours, so I'm curious which 
particular difference between the systems makes the most difference in 
the rendering speed.

I suspect the two most relevant factors are CPU and GPU.  First, I only 
have an Athlon XP 2400. Second, my mobo is a 7NIF2, so I'm using the 
integrated MX 440.  Do both of these have a big influence, or would you 
say one is more important than the other?

I'm curious mostly because I still see some tearing when playing DVDs 
and I'm wondering if I should upgrade the video card or the CPU.  I'm 
very happy with the current quality of my TV output, though that might 
change if I switch to HDTV.

Thanks.
