I recently had the opportunity to pick up a PM G4 gigabit model fitted with a wonderful Powerlogix dual 1.8ghz 7447 upgrade processor. The entire thing with mouse and keyboard was only $50! I was expecting the speed of the system to blow away my old iMac G4 at home. But to my dismay, the system actually felt slower in daily general usage. Just simple things like loading webkit and loading up a few pages felt about the same, or even less responsive compared to my iMac G4. I tried reinstalling Leopard from scratch and the system responsiveness remained the same. It came fitted with a Radeon 9200. I tried out my 6200 at home which smoothed out system animations, but the system still generally felt slow. I ran Geekbench and got a decent 1350 score, so I know its performing around the level it should be, but in general usage it just doesn't feel fast. RAM is maxed in the system at 2gb. The only limiting factor would be the system bus. I know people made a big stink back in the day over the aging 100mhz system bus in the old powermacs, but would the jump to 166mhz in my iMac G4 make this big of a difference in system responsiveness?
