Just curious to anyone who's bought and received their 2.26GHz 8 Core Nehalem mac pro. How are you liking it and especially the speed?? Are some of you coming from the previous gen 8 core models?? No matter how I keep thinking or customizing the 2.66GHz model which I want is too much and I already know within 3-4 years I'd upgrade again so might as well get the base model. And it will be a hell of a lot faster than the mini I already have.
