ASUS has updated their GTX 1080 Strix with a few more features than the previous models in this family.
The aesthetics are a bit different but there is more to the card than that, hidden under the front edge of the card are two four pin fan headers which allow you to connect two case fans to the card which will react according to the heat load on the GPU. The new DirectCU cooler has five copper heatpipes and the PCB has eight-plus-two power-phases.
There are two models, the ROG Strix-GTX1080-A8G-Gaming and the ROG Strix-GTX1080-O8G-Gaming, with core speeds of 1670/1809MHz and 1759/1898MHz respectively
