Still wondering why there's no Xeons here... would get much more bang out of this system for what your doing.
Almost all CAD programs use OpenCL/ OpenGL, some also use CUDA. Solidworks and Inventor use OpenCL (they might use CUDA, but it's a non-issue, seeing how poorly GeForce cards do in CAD programs.. see below).
The real issue is, 680's are junk for Solidworks. sw-02 is the Solidworks bench, I believe version 2011.
So OP, that's the main reason not to go with 680's for Solidworks. That and, as you were saying, the V5900 is actually faster than SLI 680's, even if they scaled at 100%:
As for Solidworks having issues with non-certified GPUs, I never had an issue. Never had a crash with my sig laptop using Intel HD 3000 graphics, and I probably put in 200+ hours on Solidworks over the past year (yes, its school related, no it's not basic like college engineering CAD work). I'm sure companies like to keep it certified. In reality, I'd *guess* the main issue is that people update drivers too often and screw something up.
At any rate, no harm getting a V5900, but a 7970 will probably give you a high enough framerate, and you won't need a 2nd graphics card for gaming.
As for dual Xeons, I don't think you'll need those for any sort of CAD work - CPU power is only really needed for a final render (you'll get the same performance while working on a model with 2 cores @ 4.6ghz, as you would with all 6 at 4.6ghz). For example, I could do a 2560x1600 render of a 30MB assembly in about 30 minutes high detail (about 8-10 hours for ultra detail - I could barely tell the difference in image quality, doubt it'd even show in a high-quality print, definitely not on a projector) with a 2.1ghz i3 dual-core. 4.6ghz hex-core might take 1/6 the time.
