HD 3850 AGP lockup with OpenGL load

[bridgman]

I doubt you will see any significant performance difference between AGP8x and AGP4x. Even 2x won't make that much difference.

And GLXGEARS IS NOT A FREAKIN' BENCHMARK

Seriously, all glxgears does is draw flat-shaded triangles and clear the screen a lot. No textures, no shaders, none of the things that modern GPUs spend their transistor budget on. An old card will usually outrun a new card on that kind of test.
