I'm planning on getting an iMac 21.5 primarily for music production via logic, along with basic internet surfing and word processing. It's always been a dream of mine to produce electronic dance music, so my productions will eventually be pretty track heavy and dense. I've already decided to get 16 GB of ram, but will the fusion drive help as well? I want to make sure there's never any lag or CPU overload. Would the fusion drive help out with performance in logic? Thanks.
