Thanks Mark.
I have a dual G4 1.2 GHz and a 1.5 Power Book. Although the dual processor would multithread the Power Book's CPU is slightly faster. I guess I would have to try it. My third computer would be left out of the loop since it's only a 500 MHz ibook. I just hope Eovia comes out with the special upgrade price again. Money is in short supply these days, my wife just informed me that we are about to expand our family by adding one new little member so I got to watch where the money goes more carefully then ever. Do you have a wireless network?, can it even be done through Airport Express? Thanks again for the info.
