I am a soon-to-be college graduate interested in editing. I am pretty well grounded in FCP, but I want to learn Avid to make myself more marketable. Thus far, I've been editing on a 2.4 C2D Macbook Pro, and the export / render times for HD are decent but are starting to get on my nerves. So, is there an upgrade to the Mac Pro line within the next 3 months, or am I safe buying now. Also, what spec do you guys recommend for the newest version of Avid Xpress? I was thinking of opting for 4gb (or even 8?) of ram, but what else do you guys recommend.
