Hello,
Well, my card is actually GTX1060 but I didn't bought it especially for
calculations.
Just from my built-in curiosity, and I know the game is not worth the
candle, I want try to run it anyway and close that 'chapter' of my life
:) I will post here some tests results - as I was looking for this type
of data, and maybe this will save some time for other seekers.
Mr Spiga, as the best expert, could You please give some guide, any
informations what and where to change in source of QE-GPU?

The only catch, which Mr Spiga always points out, is that the DP performance on
GTX cards is very slow , which is like 1/32 (or 1/24) of the Single Precision
So GTX 1070 is not worth using. A little bit of tuning of your input, better
compile flags and the CPU will perform the same or faster than the CPU+GPU.
Because you have a GTX 1070 it does mean you must use it. If you buy a GPU only
for QE, do not buy that model. Very simple.
