I didn’t mention this yesterday because the thought hadn’t really occurred to me, but the Dual 2.0 G5 isn’t very fast with only 512MB of RAM. In fact, I did a quick test with iPhoto. On my 12" G4 iBook (is it 1.2Ghz?) the photos load as quickly off my external Firewire drive as they did when I only had 512MB of RAM in the G5. I added 2 more gigs of RAM this morning, and the G5 is smoking fast now.
