I really can't give any benchmarks, as I don't have a program to do it. But,
I use ADPro to render gif images for presentations, and I have noticed a
dramatic increase in the speed at which the images are converted from V-Lab
format and rendered. Haven't had a problem except for some software left over
from my 2000 and wb 1.3, mostly games, which have a little trouble. Good Luck.
