Either an Intel Core i7 980x with a single hard drive and stock cooler, or an Intel Core i7 950, with an after-market cooler and solid state hard drive. I use Mathematica 7, Maple 14, along with Pro Tools M-Powered, all during multitasking with the typical office and internet browsing applications. Of course, I will not be utilizing all 6-cores, but it is all about lasting the longest while still remaining relatively up to date specifications.
Looking forward to hear your advice and happy new year!
