Ok well lets say the powermac g4 is a 733 mhz Digital Audio and that it will probably be running leopard by the time my ethernet thingy comes. Would the situation above still work, or do I have to have tiger or older as my OS? (Yes I know leopard is not officially supported on lower than 867mhz but since my G4 has the max 1.5GB of ram it runs perfectly fine).
