The GTX 670 is a scaled down GTX 680 in every aspect including price.  1344 CUDA Cores is 192 less than the GTX 680, baseclock is reduced 91MHz to 915MHz, 16 less texture units for a total of 112; the memory remains the same at 6GHz.  Most important to consumers is the reduction in price, down $100 to an MSRP of $400, targeting it directly against the HD7950 at its new price.  [H]ard|OCP’s testing does not favour AMD as the GTX 670 shows an obvious performance advantage over the HD7950 as well as the still available GTX 580 and does it at a price point which matches AMD’s new prices. 

Ryan’s full review can be read here, where he tests out Galaxy’s GTX 670.

"NVIDIA’s next generation Kepler GPU continues with the launch of the GeForce GTX 670. This GPU is positioned to provide great performance at a price level $100 less than the GeForce GTX 680. Could this be the best performing $399 video card, besting even the Radeon HD 7950? We tell you all you need to know if $400 is your price range."
