It looks like Gigabyte is the first to release a mini-ITX friendly GeForce GTX 1070 graphics card. The GeForce GTX 1070 ITX from Gigabyte (model: GV-N1070IXOC-8GD) features a PCB that is only 16.9 cm in length. This makes it the perfect graphics card for your small form factor mini-ITX build.
The card features a single-fan aluminum fin-stack cooling solution that consists of a dense aluminum fin-stack and three copper heatpipes, ventilated by a 90 mm fan. The card is the default 2-slot card and it draws power from a single 8-pin power connector.
As far as clocks go you get a factory-overclock of 1531 MHz core and 1721 MHz in Gaming Mode, and 1556 MHz core and 1746 MHz boost in OC Mode. The memory remains untouched at 8.00 GHz (GDDR5-effective). Display connectors include two dual-link DVI, DisplayPort, and HDMI.
