<p>Hello, <br>
</p>
<p>Well, my card is actually GTX1060 but I didn't bought it
especially for calculations.</p>
<p>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 - <span

for</span> <span>this type of</span> <span>data, and maybe
this will save some time for other seekers.</span></span> </p>
<p>Mr Spiga, as the best expert, could You please give some guide,
any informations what and where to change in source of QE-GPU? <br>

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.
