Pros: Used primarily for 3dsMax w/ iRay rendering. This is a dramatic step up from the Fermi-based Quadro 4000. I'm running this K4000 with half the processors and the remaining Quadro 4000 turned off and getting incredibly quick renders. HUGE savings on power consumption, 80W-Kepler vs. 142W-Fermi.

Cons: Not directly saying price is an issue, but for the generational jump of 2Gb to 3Gb I was expecting more memory. It seems like they almost took a step back in memory quantity and focused on the stream processors.

Overall Review: Needless to say, I bought two K4000's. Which was $400 less than just buying a single K5000. hmmm...
