It was similar with Tesla back then.

Looks like a complete redesign of the app is necessary to use Tesla`s and Titan`s properties optimal.

Everyone knows the answer is 42.
To paraphrase Jason, He's pretty pleased that his code scales so well on new architecture. There's still a lot of optimisation potential left.
Currently the Titans underperform (when you compare to e.g. a 690) by about 30% - IOW from the specs you would expect some 30% more speed.
According to Jason, drivers for new cards take a year or so to mature - in that time there's quite a bit of speed improvement (from our POV), so I'd expect when the drivers are good, the Titans scale according to their specs. Still a lot of potential left and a lot of stuff to explore.
To me, looks like the wrong bandwagon to jump on.
Mike:
I totally agree William.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
no news, machine running standard frequency produced continous ~ 2,1 Mio/day as before
_heinz:
After testing and running Zdenek's compiled app CC2.0 for GTX570 and Titan daily output increased up to 4,3 Mio/day on 2013-03-28 ;D
first step is done.
