Play with Pascal. Nexoc also upgrades to Nvidia's new Pascal architecture now and incorporates the GeForce GTX 1070 in a 17.3-inch notebook. High performance meets a high-end case and decent input devices. We were only bothered about the fans and the temperature increase.

I've had one of these laptops for about 4 months - the price was great, the customisation options were great (I already had an SSD so it was great to be able to select a build without a HDD at all), and the performance is great.
But... the fan noise is unbearable. It is far, far too loud. Opening up the case thee is a lot of spare space for things like 2x 2.5" SSD, 2x M.2 etc... I think in the next revision they really need to improve the cooling capabilities or somehow make the fans quieter.
I'm also having big troubles updating the Nvidia drivers - they fail every time. I still havn't completely resolved it.
Well mine CRASHED for good; It's RIP as after about 3 months of gaming on it the GPU died with no possibility of repair :)
So I can say with definite certainty that I am never trusting Clevo / Sager / Nexoc (or whatever name they decide to brand their products under) ever again, period!
