I have just one question: if the i860 is SO good in rendering, why does
ProVision use, for the graphic boards, the i860 (for 3D trasformations) and
a Toshiba HSP Polygon Processor for the Gouraud rendering?
I must admit that I don't know the performances of both the TI34020 and the 
HSP, nor their prices, so I can't tell if the TI340x0 debate can properly
turned into a HSP debate.
