I have a G3 400mhz B&W ppc running Jaguar. Its horribly slow at some tasks, and fantastically fast at others. I find its very slow during graphics redraws, even with Quartz Extreme activated on my PCI Radeon 7000. For example, a lesser PC (my 300mhz laptop running Win2000) running internet explorer will redraw scrolling pages much much (scientific calculation :) ) faster than my mac. On the other hand, I can seem to run more applications with less slowdown on my mac. I figure the graphics slowdown is due to the fact that just about everything on the desktop is vector, dynamic resizing etc, everything is skinned. I compare it to running Enlightenment with a really really heavy theme. Not to mention all text on the screen is very very antialiased.

oh well..
