Posing w/ P4 ("Poser Artist") under Classic and Posing w/ P5 on my old Cube was roughly the same, performance-wise. Now, compared to my Pentium 4m-based PC (back when I last had Windows XP Pro on it), posing was slower on the Mac, but render speeds were roughly the same. The Cube had a 1.25GHz Powerlogix G4 on it w/ 768MB of RAM. The Intel box is a P4m 2.5GHz w/ 1GB of RAM on an Intel 845DB motherboard. Monday should see my dual 1.8 GHz G5 show up, and I received the extra 1GB of DDR2 RAM in the mail today. I suspect it'll run faster than the P4 ever did, at least judging by the few Pentium 4 vs. G5 benchmarks I've seen here and yonder. /P
