The open source or linux programs seem to be the best options for comparing a variety of different hardware. I had never run blender before, so I went looking. I found a download for the application here (macintosh garden seems dead now?):
download.blender.org/release/Blender2.56beta/

The version that I used is Blender version 2.60 (The last official PPC version available from Blender.org)
