I think my 2.16 ghz iMac may have bitten the dust (logic board might be dead) so I may need to get a new mac. I'm running Logic Pro, the latest, using basically the instruments that come with it, and have garritan personal orchestra as well. I'm doing a short film scoring job now which is orchestral hans zimmer, danny elfman kind of stuff. For the most part I do soul/blues/funk kind of stuff using EZ drummer and groove monkee grooves, recording a fair amount of guitar and vocals etc. Is a Core 2 Duo enough for what I need? The current one is 1699. Or there's the i5 or quad core whatever it is for 1999. What should I buy at this point?? Crap! Help! Thanks!
