You know if it was a 675 clock or higher sure I could see it worth it for some. This 612Mhz is a joke if manufactures are selling OC'ed GTX models with a 630Mhz clock.

Only good thing out of it is better cooler and higher memory speed, but thats it and still even then a $300-400 price increase is horrible. Getting 2 GTX's becomes a WAY smarter choice than this, heck buying a separate water cooling system for the GPU it self would be cheaper and probably could clock higher.
