In a previous life(tm), I helped port a 3D modeling and rendering system
from DOS (16 bit code) to the Truevision i860 board.  Using the early
compilers (and who doesn't?), I saw 6-8x performance improvement over a
386/20MHz.  We _didn't_ enable any compiler optimizations, so this 
could probably be called a lower bound to performance improvement.  I haven't
heard what happened to performance with the new compilers.

PS - I'm currently doing some MS level projects on the i860, including a 
simple simulator.  (Yes, I'm re-inventing the wheel.)
