I recommend CUDA 6.0 at the moment, no CUDA 6.5. CUDA 5.5 is good as well.

It is all explained in the README https://github.com/fspiga/QE-GPU. You need QE first and then you need to apply QE-GPU that works as "plug-in"

YES! This is a suitable card.

Unfortunately not. As soon I have to present a sort of tutorial "how to use QE-GPU" then I will be able to prepare a tutorial-like style material. So far, nothing official has been produced. Anyway, if you compile QE-GPU, the way to use it is _exactly_ like QE. If you know QE, you can use QE-GPU.

HTH,

Cheers,
F
