Help! New 27" Imac - Dual Core Or Quad Core For My Needs..., Would the 3.33 Ghz suffice? Options

[uvbnskoold]

Hi there community,

I have asked this question of many other people and forums but no one can give me a straight answer.

I compose music using Logic Studio and all included sounds, VSTs and a lot of different libraries (EW/QL samples) with very little live recording.

I want to upgrade my system (currently using a dual 2.3 Ghz PowerMac G5 with 8 GB of RAM) to one of the new 27" iMacs - definitely going to go 16 GB of RAM and a 2 TB HD, but I'm torn as to processor.

I just don't know whether the 3.33 Ghz Dual Core processor will be adequate or I should wait and get one of the Quad Core i7 processors for about $500 more money, but I'd have to wait.

For what I do, will the processor make a huge difference? What I've been told is that processor only matters for audio encoding (which I am not really doing a lot of) or video work/rendering... not really applicable to composing with samples using Logic.

Any thoughts?

Thanks!
