I have compared an EVGA GTX 680 4gb Classified, overclocked, to an EVGA GTX Titan Superclocked, slightly overclocked and these are the results in my own little test scene:
Test scene 01-Exterior GTX 680 = 4.35 seconds/frame (3 star, 1920x1080, typical)
Test scene 02-Interior GTX 680 = 6.08 seconds/frame
Test scene 01-Exterior GTX Titan = 2.21 seconds/frame
Test scene 02-Interior GTX Titan = 3.35 seconds/frame
I believe that I can get a little more performance out of the Titan.
I hope this helps some with their hardware considerations.
