Hi I made my work station on Junary of 2012 with this:
Intel Core i7 2600 3.4Ghz Box Socket 1155
Asus P8Z68-V/GEN3
G.Skill Ripjaws X DDR3 1333 PC3-10666 16GB 2x8GB CL9
PNY nVIDIA Quadro 2000 1GB GDDR5
Added last month: SSD 250GB SAMSUNG EVO
Cooler Master GX 750 V2 ( too big, but still everything very cool)
Now one question: I want increase that number.
Add GeForce GTX 660 OC 2GB GDDR5 how much could increase the speed?

Zero. Update your processors.
Yeah! I've been checking all the pages and just discover that the speed is quite OK and the power to the render is given by the processor.
I thought about the graphic card because is cheap but with this speed and this solution I think that I will continue how I am.
Thank you for the answer!
