Most people don't use the CPU power for much of anything useful (on windows).

All the graphics MIPs is done in the graphics card GPU with only relatively 
sparse high-level geometry instructions done in the CPU.

All the rest of the CPU is wasted on virus checkers.

Graphics drivers on linux can be pretty crappy, so the CPU can be needed a lot 
more to emulate OpenGL and other graphics hardware functions.

Decent cad software with 3D viewing can be done on a dumb framebuffer system 
with only minimal hardware graphics acceleration. The only thing you lose is 
graphics speed when rendering polygons with variable shading, and rendering 
polygons with transparency. A bit more hardware can help with that.
