	Which one is faster in GPUGRID?

	According to the performance chart at the bottom of the performance page: GeForce GTX 960 GTX 960 GTX 670 2048MB 4095MB 2048MB N = 193 76 201 Average = 15.77h 16.43h 16.49h Minimum = 8.1 h 11.1 h 10.1 h Maximum = 24.3 h 24.4 h 30.3 h So these two cards are almost identical regarding the processing time, however I would chose the GTX 960 because it consumes much less electricity.

	I would choose the GTX 960 too. But there is a bit of a memory clock problem with the GTX 960/970/980 (but not the GTX 750 Ti). On all GPGPU work, the memory clock defaults to the lower "P2" state, apparently to protect the card from excessive heat, or maybe to avoid errors, as compared to the "PO" clock used for gaming. The problem is describe here: http://einstein.phys.uwm.edu/forum_thread.php?id=11044 The solution is to use Nvidia Inspector as described here: http://einstein.phys.uwm.edu/forum_thread.php?id=11044&nowrap=true#136598 It works for me with only a slight increase in temperature, though I have not tried it on GPUGrid.
