I have a few questions about upgrading my RAM in my iBook G4 933: 1. I would like to get into Final Cut Pro Express 2, and since I have 256 now...Should I get a 512 stick becuase there is only one port on the board right? 2. Where is the best place to get good ram for a good price? I looked at crucial and they had a 512 stick for 107.00 is there a better place than there? 3. I'm pretty computer literate, so there shouldn't be any problems of me installing my own ram right? Is there anything I should look out for when doing it? thanks.
