New Geforce GTX 680m only showing 960 CUDA Cores.

My new GTX 680m is showing only 960 CUDA Cores in Nvidia-Settings panel. The spec page on the NVIDIA website says there should be 1344 CUDA cores on this card, what gives?

You might have a fake rebranded Chinese GTX 680m. ;-)

Its showing as a 680m in the Nvidia-Settings, How do they fake that? Also, this product originated in Califonia.

I can easily burn a BIOS under which nvidia-settings will show that I have a GTX Titan, instead of my current GPU.
