Many CUDA or otherwise GPU accelerated professional productivity apps will...

- Not have an SLI profile, especially in the consumer drivers, so there would be NO advantage to having 2 cards. You really only see multiple card support in science/financial research apps anyway.
- Not have ANY support/certification for use in the pro apps.
I suggest building 2 machines instead. One machine, a "work" build with a workstation class GPU, potentially on workstation motherboard/cpu hardware, the other, a "weekend warrior" with an i5 and a gaming GPU on a cost effective 1155 MOBO.
The 3930X machine with a GTX680 is only good for maybe a 10% average improvement in gaming performance over a much less expensive i5/GTX670 rig, and will fall short of the performance in pro apps that you would get with a properly selected workstation GPU. If you're careful about where you dump the funds, you should be able to build the 2 machines, for about the price of your planned "super" rig. In the end, you'll have 2 machines that can actually perform each-others function in a pinch if one of them goes down.
