I just bought a very similar laptop as yours in the thread. Just with an Geforce 765M instead of the 860M - but it's very similar in Performance (but 860M is better ;-) ). Comparison here:http://gpuboss.com/gpus/GeForce-GTX-860M-vs-GeForce-GTX-765M
And I'm very satisfied with the Performance (although I can't say anything about the Dk2 Performance of course.. ;-) )
But because it is my first laptop, I had to learn two things to get that satisfying Performance (and ist maybe helpfull for you ):
1) I had to set up the right GPU for the Demos: The i5 has an built-in GPU. Enough power - but runs on low energy - for standard application. So it was set as default on the laptop. Unfortunately it was not enough power for the demos... But after switching to "use Geforce" as GPU for the Demos it runs very good!
2) The laptop ( I think all work similar, at least with such high Performance GPU built-in) automatically reduces the gpu power when running on Akku instead of using an attached power cable! AFAIK you can't (and shouldn't also) switch this off! Keep that in mind!
Just my two Cents...
