CAD build, critique needed

[Martell1977]

I have built several computers for myself and clients, however they have all been for gaming. I now have a client asking for a machine optimised for CAD. He has given me a parts budget of $2,000.

Total fresh build and this is what I have:

The above build gets me in just under the $2k limit, I'm questioning the GPU the most (is the Quadro equilivent better for $60 more?), but the CPU and RAM are things I'm not totally positive about as well. Are the items I have chosen optimum for CAD in the price limit I have?

Maybe he can wait a while for the new Bulldozer CPUs, they look like they'll be just what he needs. Scheduled in early June.
