I'm want to have my new Mac Pro roaring almost out of the box when I bring it home on Friday (the first day it's available for pickup in Apple Stores, is my guess). The plan is to buy RAM ahead of time (can't stand the thought of having to suffer with 3GB of RAM even for one day, let alone the whole weekend (I'm not paying the Apple RAM tax, no way!). Any idea if the current chips will be compatible with the new MP, or will the 2012 MP use some new kind of chips that may not be available from 3rd party sellers for a few weeks or even months?
