I'm trying to get a game plan to build a couple pros for my wife's small business. I want to make them as future proof as possible but save money where I can. So my understanding from searching is that I can do a firmware update on the 2008 model that will essentially turn it into a 2010 model with a different CPU and graphic card. (could find a guide on doing this, anybody got a link?) I'm wanting to pick up the hex core 3.33 as my primary CPU. But can I buy a dual CPU computer and only update one of the chips at first? That way I could always upgrade the other down the road if adobe ever gets more efficient at utilizing more cores. Has anybody done this with stable results?
