We've already seen many other AIB partners and their custom GeForce GTX 1080 cards, but there aren't many custom GTX 1070s in the wild... yet. Nordic Hardware have the ASUS GeForce GTX 1070 Strix in-house, with a triple-fan cooler and increased GPU clocks.
ASUS has clocked its GTX 1070 Strix at 1650MHz Base, and 1860MHz on the Boost when in OC mode - compared to 1683MHz Boost on the GTX 1080 Founders Edition. ASUS has continued to use just the single 8-pin PCI power connectors, and another HDMI 2.0 port in the place of the third DisplayPort output, which is meant for VR headsets like the Oculus Rift and HTC Vive.
We have an MSI GeForce GTX 1070 Gaming X 8G that we'll be reviewing shortly, so it'll be good to see how the ASUS GeForce GTX 1070 Strix performs against it.
