The most noticeable feature of this GTX 1070 from MSI is that is has an additional 6 pin power connector intended to ensure smooth power delivery.  The most confusing part is the branding, a GAMING X is better than a GAMING Z which is better than a GAMING which is better than a non-GAMING 1070.  The factory overclock on the card pushes the boost clock to 1771MHz and [H]ard|OCP also tested it the best overclock they could manage, a base clock of 1692MHz and a boost clock of 1882MHz.  Check out the effect that had on gameplay in their full review.

"We have MSI’s new GeForce GTX 1070 GAMING X 8G video card to evaluate today. We will push this GPU as high as we can, and see how the overclock compares to the default factory overclock, and a Founders Edition NVIDIA GeForce GTX 1070. This video card is a fully custom retail video card with the Twin Frozr VI cooling system. "
