Hi gang, I'm new to this list and would and in connundrum land. I want to buy a new Mac. I will also be purchasing Logic Pro and probably an Apogee duet. Here's the thing. I've read all sorts of swell stuff about the iMac Quad-core, and the price seems reasonable enough (for a Mac, anyway). You get the screen, the slick look, the power. But there are no options for expansion slots. More to the point, there are no PCI slots should I want to get something like a Universal Audio PCI card loaded up with their sweet plug-ins. They rock and they handle their own processing loads nicely. Which led me to thinking about getting a Quad-core Mac Pro tower. Here's the thing about the current Mac Pros: Huge discussions on MacRumor boards about problems associated with excessive temperature levels in/around the Xeon processor chips when it comes to audio processing, even from just running iTunes. Kernels frying, motherboads melting, Apple being cagey with head in the sand, that sort of thing. I would very much like to avoid that kind of trauma. So. What are my options here? (besides waiting 6-12 months in hopes that Apple fixes the heat problem.) I want a quiet, reliable machine to do home studio recording. I do not have an unlimited budget and fear getting burned, so to speak. Any advice would be greatly appreciated.
