I just won an ebay auction, kind of by accident. I've been wanting a Power Mac G4, and I was "alloted" 100 dollars to go for one, so I just make a maximum bid of 100 and see what happens...this one I nabbed for $81 dollars. Anyway, here are the specs: Power Mac G4 400mhz (AGP) 512mb ram (1 dimm) 80 gig HD dvd rom OS 10.2 I'm planning on laying Tiger in it, and possibly looking for a cheap CPU upgrade. Does anyone know of some good places to start looking for one? probably no more than 1 ghz, and I'd like to see it at 150 dollars or less. How well would Tiger run on this machine with the current CPU? My past Macs have all capped at Panther, so I'm not really sure how to gauge this one.
