The performance I'm getting on garageband 09 atm is pretty poor. The sound constantly breaks up while I'm playing the software instruments. The playhead goes to red which I know means the processor is overloading so I assume that'd mean I have to get a fast processor. Atm I have a 2Ghz core 2 duo. I was thinking of upgrading to a 3Ghz processor. Would that solve the problem?
