Hi, I have a 867 MHz Powermac G4 that I just cant get rid of because it simply wont die and I also don't have the money right now to upgrade to a new computer. I just started taking classes for web development and although a newer G5 or intel mac would be ideal and required for using Adobe CS4... I'm gonna try and get by with this G4 for at least another couple of semesters. Hey, it's taken me this far (8 years!) I maxed out the ram to 1.5gb about a year ago and I've been very happy with it so far. But now that I need to have multiple applications open at once, mostly Adobe CS3 applications, It gets a little slow and glitchy and I'm starting to see a lot of that little rainbow spinny thing while I wait for my mac to catch up. With all that said, my question to you guys is if its worth upgrading the processor at this point or if that would be a waste of money. I know the minimum requirement for running CS4 is a G5 and I just want to say I'm OK with using CS3 for now. I look through ebay every now and again and see processors from higher end Quicksilvers going for anywhere between $150 to $300. What processors would you recommend? Can I replace my single processor with a dual processor? Like the Dual 1.0GHz G4 from a "Quicksilver2002"? Could I install that without other modifications? Would that give me that little extra "umph" I'm looking to get? Are there any other options I'm overlooking that would allow me to get more out of my current machine? Thanks in advance!
