I may make a trade in the near future for a powermac g4. Its got a 500mhz cpu in it, which isnt supported officially, but i can install leo anyway, right? The question i have is how well would leo run on such hardware? Its got 640mb ram which isnt much, but not bad for an old g4. I plan on using this mainly for garageband and i would just install tiger and ilife 08, but apple doesnt uderstand backward compatible file formats so any songs i have worked on recently require ilife 09. I dont plan on editing on this machine, just recording single tracks while the software instruments play a backing track. Can this machine handle this or am i asking for a major headache?
