I know the VGX can do a million FLAT shaded polygons (triangle meshes
with 50 pixels per triangle, actually), but I've never seen anything
from them claiming 3 million "polygons" [have to be careful to say
exactly how big and what kind of polygon], especially not Gouraud
shaded polygons.

However, one of the parallel architecture machines (I can't remember
if its pixel planes or AT&T pixel machine -- I always get them
confused) does claim to be able to do 3 M Phong (note: not Gouraud)
shaded polygons.

I saw the 730 at SIGGRAPH and I don't remember them claiming this.
Where does this number come from?

>I worked on the IBM and I couldn't really see my objects being built !!

Can you say "double buffering"?
