8 core what? Woodbridge, Cloverfield, Nahalem, Westmere? Pro-tools can be run on a single core chip. Depends on your expectations. The performance of the 8-core Mac's differ greatly with generation. So maybe a little more info. I'd get more memory than anything else if you are running everything on the host without DSP. Get at least 16GB of RAM from 3rd party. The verdict is out on Pro-Tools scalability over cores which is what you need to figure out. The Quad 3.2GHz may be faster on host plugins than the 8-core at 2.26 or 2.4GHz but the 8-core will beat it on mixing. Hard to say. When you are recording, a high clock speed is best. When mixing, lots of cores are better than clock speed. Or do what I did and get the 6-core 3.33GHz. The best of both. It is faster than the Quad and all the 8-cores except for the 2009 8-core 2.93GHz. But it will be faster when tracking. Hope some of this helps.
