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.
Pro Good build quality
The plastic body is lined with metal accents which add an overall rigidity to the card. The aesthetics are nice as well and the GTX 1070 FTW Gaming ACX 3.0 manages to appear sleek and robust without appearing ostentatious.
Pro Compact size
With a length of 267mm and height of 128mm, the GTX 1070 FTW is one of the most compact 1070 cards available.
Pro Lots of headroom to overclock and tweak
The FTW ACX 3.0 leaves a lot of room for tweaking. You can overclock for up to +147MHz Core and +176MHz Memory without adding any additional voltage.
Cons
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.
Con The cooler could be better
EVGA GeForce GTX 1070 FTW Gaming ACX 3.0 does not do a good job at keeping cool temperatures. It's usually around 47 degrees C when idle, which is 8 degrees higher than what the reference card manages to achieve at low usage and 75 degrees C under load. This admittedly is lower than that of the reference card but still higher than any other custom GTX 1070 card.
