Hi, I've been a logic user for about six months, and just purchased the East West symphony gold pack and expansion pack. I currently have a G4 Powerbook 1.8 Ghz w/ 1GB of RAM, and I was told at a mac store that that's not really enough to handle the power of East/West. Also, I already push the limits of Logic with the stuff I do now. I'm planning on doing some more orchestral work now, so I think I'll have to use even more power. I'm looking into buying a 20 inch iMac and upgrading the Ram to 2 GB and upgrading from 250 to 500 GB on the hard drive. The processor speed is dual core 2.16 Ghz. This I could get for 2000. I could also get the MacPro, which has two dual core processors at a speed of 2.66 Ghz, upgrade to 2 GB Ram, and get the same hard drive. But, even without a display, that's about 3300. Is it worth that much money to get the MacPro? Do I need that much power, or will the iMac be fine? I want to get something I won't have to upgrade for a while, and use for a long time. I know the MacPro is more upgradable, so maybe is that the better investment? I'm not a Mac expert by any means, but hopefully there are some out there that can set me straight! The guy at the store says the iMac should be plenty. Let me know what you guys think...thanks!
