I'm speculating over the performance of 10.3 and the G3 processor. The G3 processor, is, for the most part, an ancient thing. However, it still has to be supported because Apple still has G3-based iBooks (now @ 900 MHz). So my question is - will a powerful G3 processor, specifically the 900 MHz clocked one, be able to run 10.3 well (assuming it has 32 MB + of VRAM for Quartz Extreme)? I know that 10.3 is optimized in one way or another for the G5 (PPC 970) processor, but will that kick G4, or even worse, G3 users out of the "good performance" line?
