I gather from looking back into the posts that Kontakt isn't optimized for dual processor machines.

Does anyone know if and when it will be? And also what exactly the advantage will be in the functionality?

I'm currently running GPO on a G4 laptop and am considering a desktop, also Mac. So the question becomes whether to go with a dual G5 or stick with the iMac G5's that will be out soon.

A related question: I also saw in past posts that for some reason Kontakt can only utilize 2 Gb's of ram - is this still the case?

I assume that these issues are relevant to GPO users as well.
