I have the same videocard and even your same monitor!! On the other hand, I use Win7 x64. Still got the same problem, though. I am convinced it's a bad flaw in latest releases so I guess we have to wait for the team to fix it. 17.3.x releases should be fine, though. You could use one of those releases to have something more recent and optimized.
I think AMD raged at Dark Souls 3, so that game wasn't tested on driver release, I'm sure if you send AMD a bug report the issue will be fixed.
