Not very good for crunching. In Europe the 750ti costs the same as the "old" 660GTX,
but the second one has 150% power related to the new maxwell.
For energy purposes the new one is better but both have low power consumption.

plus a question : if I have two ATIs running how do I add a Nvidia in third PCIe port for different projects like Einstein or GPUGrid,
tried this often before but it never worked as I had expected. Used a cc_config for these trials.
