Yet another Ram thread... I got a 1.6 G5 powermac with 512mb. I run Classic with Quark and Nisus simultaneously with OS X Nisus, Word, iTunes mail yadiyadiyada.... iPhoto has about 2000 pics too. Am I wasting my money upgrading to 2.5 gigs versus 1.5 gigs? I know the adage is more ram more speed, but is it worth the money for one on a slight budget? It's like 200 vs. 400 dollars at OWC. Thanks for any input, particularly personal experience with similar upgrades.
