Gentlemen?,
NVIDIA will sell far more of these - my wild guess is $4,650- than we mere mortals might expect, as the visual aids for the advancing realm of the Personal Supercomputer.
The recent increase in availability of of 4X and 8X CPU, 8 and 10 core CPU's (10-core Xeons are $3,500+) supporting up to 4TB of ECC RAM - that's a $35,000 story in itself- plus the important advances offered by PCIe coprocessing modules such as Tesla K20 and Intel Xeon Phi will bring> atmospheric, oceanic, astrohysical, chemical, metallurgical, and particle modeling, CGI feature film animation/ editing, gas, dynamic structural, thermal, mechanical, financial, resources exploration, and aerodynamic simulation to a new level of accessibility- well relatively.
The Titan supercomputer at Oak Ridge, currently the most powerful calculating machine in the World, is using massively parallel components of which the bulk of the fundamental components > AMD CPU's and the Tesla K20X coprocessors are a $97,000,000 configuration of multiples (18,600+ of each) of components found at newegg and amazon. That's the key to all this- string together many, semi-consumer level parts into a massive system > it's AI Modular Man! And the Quadro K6000 as an extreme performer will be one of the big picture windows to those events.

PS > And yes, the K6000 is guaranteed to be SLI- capable as are the Quadro 6000 and K5000 along with the Quadro FX 4800 (1.5 GB) and FX 5800 (4GB) of two generations ago.
