Intel i5 or i7 for Logic
I'm looking to upgrade my music setup from a MacBook Pro Core 2 Duo 2.5GHz to one of the new 27inch iMac's. I'm specifically looking at either the Quad Core i5 or the Quad Core i7. Money is tight so don't want to spend case unnecessarily. Logic Pro 9 is going to be the main application in use amongst a host of plugins such as Sprectrasonics Omnisphere, Kontakt, East West Symphonic Choirs etc.
Do any of you have any real world examples of the performance of either of these iMac's?
Thanks in advance
