I just built mine two months ago (clean windows 10 install), and I was really hesitant on Windows 10. Last year there were many gamers complaining about driver issues and FPS drops. I went ahead with Windows 10 to avoid the whole nagging forced upgrade issue, and I will admit I like 10 much better than 8.1. Now that it's going on two years old, most of the issues are gone, and I haven't had a single problem with any of my games. The navigation and organization of Windows 10 is much better than 8.1, more like Windows 7 was. I'm happy to say I like Windows 10 much better.
