Some improvements, but not across the board. We still have ArchiCAD 8.2 to look forward to (March 04 ? with Apple recommended improvements). ArchiCAD 8.1 and Panther overall feel very responsive on the newest configuration.
additionally - 8.2 is specifically being developed for speed improvements on Mac OS X..

My local reseller of ArchiCAD, guaranteed me that the Graphisoft has at this moment 7 seniors programmers working in the improvement of ArchiCAD 8.1 performance in the Mac OS X. If they (GS) gone a call it 8.2, I don´t know.
I think to compare the G4 to G5, that you need to see how the G4 runs with 8.1 with the same RAM. David, I don't mean to make work for you, but the G4 may look better than you think. 1Ghz vs 2Ghz the G5 should show that ratio of improvment.

I was using 8.1 on a G4/800 with 1 gig ram. My dual G5 with 1.5 gi ram reduced the same rendering (sketch) from 12 min to 1 min 40 sec. Not exact, but clearly a hugh increase....for what it might be worth.
