Our group is considering replacing our 2500T workstations with
Personal Iris workstations. Can anyone comment on the following
questions? Mail repsonses directly to me and I'll summarize the
responses in a subsequent post.

   - How do the two workstations compare in terms of raw
     compute power and graphics speed? Our application will
     consist of simulating mobile robots over rough terrain.
     The terrain will be ~10,000 flat shaded polygons.

   - Given the above specifications, what sort of frame rate can
     we reasonably expect?

   - How important is having Z-buffer capability for our application?
     Are higher frame rates achieved by using Z-buffer or some BSP
     algorithm? 

  Thanks for your help...
