Hello again, I have a beige G3/266 Mhz PowerMac with 256 MB RAM and lookin to upgrade. I got about a $300 budget and wonderin if it's smarter to upgrade a G3 or buy a used G4. I'm been doin some pricing on upgrading and so far I've have a plan of getting a 900 Mhz CPU upgrade (PowerLogix PowerForce G3/1GHz (1000MHz) ZIF), 512 RAM upgrade (total of 640 replacing two 64 MB RAM sticks) and a 120 gig HD. I was lookin on eBay and G4s are sellin from $200 or so with a little less Mhz, ram and storage space. I dunno if an upgraded G3 is more cost efficient than just buyin a G4. I don't know, what's yer opinion?
