Pros
Pro Excellent cooling
The massive size of this GTX 1070 card is justified by the excellent cooling capabilities is offers. On idle the temperature gets as low as 36 degrees C and around 39 degrees C on light load. And this is without the three 90mm fans turning on.
On full load it rarely ever surpasses the 65 degree C threshold and it's usually somewhere around 58 degrees C most of the time.
With these temperatures, the Zotac GTX 1070 AMP! Extreme provides the coolest experience out of all GTX 1070 cards on the market.
Pro Good build quality
The Zotac GTX 1070 AMP! Extreme is wrapped around in Carbon ExoArmor for protection which gives it a robust and "premuim" feeling. As usual with Zotac, the GTX 1070 AMP! Extreme has a great minimalistic design. With 7 different colors to choose from and 4 different lighting effects.
Pro 5 year warranty
Pro Nice looks
Despite the yellow on the back this GPU with the carbon look is very nicely designed.
Pro Good build quality

Around the backplate Asus has included Aura RGB lighting with a wide array of different effects available, making the ROG Strix a good choice for building a rig into a windowed chassis.
The effects and color can be customized by installing an additional free utility which is also pretty lightweight.
Pro Above-average cooling
The triple-fan cooling system and the optional fans you can add push ROG Strix' cooling performance to above-average levels for a GTX 1070 card. Without any additional fans and under heavy load it will rarely surpass the 61 degree C limit with only the Zotac GTX 1070 AMP! Extreme having better cooling.
Pro Additional fans can be attached for even better cooling
There are two four-pin headers at the end of the PCB used to attach additional fans. These headers can be used to improve even more the excellent cooling that the ROG Strix provides.
Pro Has a second HDMI port for added Virtual Reality compatibility
Instead of having three DisplayPorts like most GTX 1070 cards, Asus have opted to exchange one of them in favor of an additional HDMI port. According to them, this change has been implemented to make it possible to attach both a VR device and a display at the same time. This increases VR compatibility since there have been problems with DisplayPort as a conduit for VR headsets.
Cons
Con Odd design
The yellow on the backplate does not suit most builds.
Con Quite large
The Zotac GTX 1070 AMP! Extreme is a rather large card. It effectively occupies the space equivalent of a 2.5 slot.
Con May need a support bracket to prevent from sagging
Since the GTX 1070 AMP! Extreme is quite heavy, there's a risk of it sagging while mounted on the motherboard. This is why it may need a support bracket to prevent it from doing so. Unfortunately, Zotac has not included a support bracket so you will need to find it on your own.
Con No true RGB
It only has 7 colors to choose from.
Con Very expensive
Con The Aura (RGB lights) software can be better
The software that controls the backlights can be better and has some missing features which feel like it would have been pretty easy to bake them in, especially for this price and for the fact that Asus went through the hassle of adding them in the first place.
Things like being able to set the temperature for which the lights change or making the lights a certain color when playing a certain game would certainly have been a nice addition.
Con Large
As is the case with many high-end cards, the size of this card means it takes up two backplate slots but covers roughly 3 slots (including the one it's fitted to). This might limit your options for some motherboards, especially configurations smaller than ATX.
