I'm wondering if I should upgrade my parent's PowerPC iMac to an intel. Currently My parents are using a PowerPC iMac G5, so basically, the last PowerPC iMac, and I have an opportunity to upgrade to a core duo iMac... or basically the first generation intel for something stupid... like $50. Is the upgrade worth it? It's literally going up only 1 generation from 7 years ago. My parents only use it for email and internet browsing, but I see it choke once in a while... plus it kind of bugs me that I can't install Chrome or upgrade the OS because it's PPC. What do you guys think? Will there be a significant boost in performance? Is it worth the upgrade for around $50-100?
