I work part time as a tech at a PC store. A customer came in and asked if we worked on Macs...He had a B/W G3 running OS X and wanted to upgrade his processor. He complained that it ran slow and had he could not find any drivers for OS X. He wanted us to upgrade the CPU ( I almost jumped at the chance).....He may buy a PC (bad move but I can't say no to him, which sucks)....I may try to buy the G3 from him if he comes back, is it worth it? I am assuming he bought a G4 upgrade for it...it would be replacing my iMac G3 500 (was a Rev A which I upgraded with a Harmoni). Would it be any faster?
