Benchmarks

As promised, here are the benchmarks for my G4s, including the scores using Leopard. One thing I should note is that the 733mhz Quicksilver processor in the Digital Audio machine DOES win out over the original 533mhz processor. I posted previously that the 533mhz won but it doesn't look that way after I reviewed the numbers. I also included the numbers for the 733mhz QS processor in the DA board with a cooling fan (from a a Quicksilver). That seemed to make a difference in performance. I should note that there really doesn't seem to be a big difference in subjective performance ratings between Tiger and Leopard. Leopard occasionally takes a little longer to load Safari or Firefox but I think this is more due to low system memory (768MB). I haven't had much time using Leopard on the Gigabit Dual to see if it's an issue with greater memory installed.
One other thing about running Leopard on these machines is that I haven't experienced any problems so far. I've read some people using unsupported Macs are having trouble with DVD playback, Front Row, etc. So far I haven't found any issues. My guess is the people who are having trouble are the ones using the old ATI Rage Pro 16mb video cards.
