I know that the orignal question asked about CPU, however, one of the best things that we have done is to connect a projector to the machine that we use for Inventor. Brainstorming with the entire design team you can project onto a large white board and draw on the white board or design in Inventor at the same time. Ideas can be CADed up on the fly and new ideas can be evaluated to see if they will work.
