First off, does Solidworks suport SLI, and does it take full advantage of it?  If there's no suport for it, I guess this becomes a very short and easy post to reply to.

If SLI is supported, would I be better off with two Quadro 2000 cards in tandem or with a single Quadro 4000? 

Also, I have been using the famous punch holder benchmark part recently and am trying to figure out is CPU or GPU is more important for crunching the part...any insight into this?  Thanks so much for any replies.
