There are driver "hacks" in order to get these cards to work. Professional cards (in most cases) are just rebrands of consumer cards with larger frame buffers (more VRAM) and
professional driver support. For Solidworks, you're going to be drawn to the card that has superior FLOPs. I really think the Alienware computer is better suited for you, however realize that getting the card to properly support the program won't be entirely legal, but will end up the better solution in the end. Also, you can throw technical support out the window if you modify the files needed to get the card to work, but it appears that only "real view" is disabled from non-professional cards.
Anyway, here's a link for you to get that to work : http://solidworks.burkesys.com...10/realview-graphics/
Users on the Solidworks forums are split on the issue. Personally, I use a 5770 for Autodesk Inventor and experience no issues.
