I will never use Windows 10. I refuse to allow Microsoft to take away my ability to have control over my own PC with 10. I ended up going from 7 to 8.1, and everything works 100 percent without issue with my R7 2700X. As an added bonus, gaming performance is faster, and so is NVME drive speed. Don't believe the lies about AM4 drivers not working on Windows 8.1 either. The drivers for Windows 7 work just fine on Windows 8.1, and all you have to do is install them through device manager. You can make Windows 8.1 look almost identical to 7 with just a few minutes of configuring.
