Ok I'm having a pretty big dilemma at the moment. I need a new iMac for music production, within the next week. My options are as follows: 1: Get the G5, and run all of the apps I curently own without a hitch. 2: Get the Core Due, and wait until mid-summer to get my hands on the Universal Binary versions of such apps, possibly having to buy them again, or pay a fee for the update. Keep in mind that I'm not doing anything like recording bands and such, I'm merely fabricating electronic dance music using CPU intensive virtual synthesizers and such. My 1.33ghz iBook G4 just cant keep up anymore. While using my favorite synth, the cpu meter pegs instantly to 50%. I really need the extra horsepower, asap!
