Okay I'm not sure where to put this. I have a new build with an i5-6600k, gigabyte z170x gaming 7 motherboard, and a powercolor hd 7970. It seems that if I try to use the card in the x16 slot I get crashes and such, but if I use it in the x8 slot it seems to works fine. I can use my old 550ti in the x16 and it works fine. So I'm wondering what could be wrong?
