Which 1080 did you get? When researching before buying mine I read that Gigabyte and EVGA brands often have coil whine, Asus and MSI don't so much. I settled on an MSI because of this (historically I've bought Gigabyte brand graphics cards, but not this time). Can you return it?
It's a Gigabyte one. It was a complete set, so if I return it, I'll have to return the entire pc. I'm not sure I want to go through the trouble...
Oh, and nice picture :)
