My PPC G4 iMac is slow as hell. I plan on upgrading soon enough to a newer iMac but in the meantime I'd love to recover some speed. I know i have a woefully low amount of RAM - 768 to be exact - but apparently I'm stuck with that. It was running better in the past but with time things just slowed to a crawl with minimal things open - Mail, Safari and maybe Word and Excel. I gave up trying to run PS Elements 3 on this machine. That just makes me want to scoop my eyes out with a spoon. I run iClean regularly, I have my desktop clear of clutter. What can I do in the interim before I buy the new iMac to help things some? Or am I just S.O.L. and just be patient and wait for the new machine?
