Is there any real difference (real world) that can be noticed from upgrading from a 240Mhz 603 to a G3 CPU? And is there any way to get the Duo to run faster, either by getting more ram (what's the max amount allowed) or by upgrading something or chipping the mobo or something? It's 100Mhz PPC CPU is just crawling with 7.6.1....maybe I can try and reinstall. Thanks!
