I'm on an old FX-8350 and a 970. I went from 15 fps to a solid 60 simply by re-seating my GPU. This has been driving me mad all week. I've nuked my hard drives and even flashed my bios and re-seating the GPU is the only thing that finally did the trick. To be clear take your GPU out of its' port and place it back in, I used a different port this time. I hope this helps someone out there and I'd love to know in a reply to this thread.
