I doubt the graphics board is the bottleneck at this point.  A Quadro4
will do just fine. I could run it on some Wildcats or FireGLs, but why
bother? Get a CPU as fast as you can, then anything from GeForce up will
do. Actually I'd guess *any* 3D accelerator will do, as long as it has 
hardware stencil and not too crappy GL drivers. Anybody with 2 GHz and a 
TNT or onboard graphics?
