I finally got the system!!! (damn UPS crossing Canadian border). It's wonderful. In fact it does everything I need it to. However, I noticed that the hyper-threading breeds a new thing in Carrara 5. A second render block. This is wonderful, however, on one picture that I rendered, there was a seam line in between the two render blocks on the rendered image. Now, unfortunately I'm at work, so I can't show you the image, but I was curious, is there a way to shut off the second render block?
OH, and just one note. My old computer used to take forever to calculate physics. This one just produces them, without any load time.
