I'm curious about performance...I found my 6400 and 6500 to be dog slow when compared to my PCI Macs, even with 32MB Rage Pro video cards. The MacBench scores are very similar, but when playing games, the 6500, even with a G3 upgrade, was noticeably slower.
I was using MagicEngine. I'm wondering if I need to pull them out and try again...
