it should work fine. With quadro like I explained you don't need to worry much about driver problems as the support and testing that was done with it was done over a lot of actual testing hours.
Remember the quadro 2000 got almost double the performance of the 600.
If I might ask why don't you go for a better cpu like the 950 then go for a cheaper consumer card. The driver support won't be there but a stronger cpu will be more of a advantage and benefit as the expensive gpu. Plus you'll have lots more bandwidth to play with
The CPU will likely be an Athlon II X4 or an i3-2100. I'll try to squeeze in an i5-2500 (non-K), if the budget permits. Depending on when Bulldozer's released, it may or may not be a candidate.
Rendering is not such a problem. The need for a smooth workflow is more pronounced. We'll probably implement bucket rendering or have a dedicated server for rendering production quality media. Might even lease server time.
Thank you for the feedback folks. I think I'll let this thread stay alive for just a wee bit longer in case someone comes up with some "NVIDIA-card-in-AMD-rig" horror stories.
