Hey there, I have a serious question. I have a PowerMac G4 500MHz (AGP Graphics), with a Radeon 8500 Pro, 768MB RAM, 80GB HD, SuperDrive, Iomega ZipDrive (Built-in). Should I buy a CPU upgrade for the machine, a 1.2GHZ for about $260, or should I sell it, and upgrade to the Mac Mini? I could sell the video card for $120 alone, and the machine for around $400 I think. What would you do?
