Looking forward to your feedback. Solidworks should run pretty well, it's one of our test apps. Solidworks 2011 with SP3 or later enables Vertex Buffer Object (VBO) support, so you should see improved performance when viewing/rotating complex objects. However there is a know performance bug when you have complex objects selected/highlighted, it's not unusable, but it does lag down noticably, this has to do with the types of lines being drawn for the highlighting. We also test Rhino 4, but in a pretty limited manner, I'm interested in how it performs in real-use situations.
