So I have always been on the fence about upgrading from windows 7 to windows 10 for several reasons.
#1 It was very limiting in some aspects and controlling in others, such as trying to sell you on cloud service Onedrive, Microsoft office etc...
#2 They stated you will not be able to play pirated games. (This wasn't alarming because I pirate games, I use steam) but I don't like microsoft knowing what I have downloaded and being able to limit what I can and cant run on my machine.
#3 Not familiar/scared of the new UI
But a friend of mine had convinced me to upgrade to 10 saying it better for gaming. Since I trust him, I did.
And holy shiz the first game I played I noticed a BIG difference in graphic quality (Diablo 3) So I did some digging. As it turns out Windows 10 is able to utilize or better utilize DirectX 10/11/&12 features. Wheres as Windows 7 is less inclined to do so. Especially Since i am running a GTX 980 which was basically the hardware that was made to support DirectX 12.

So, in closing, for anyone (Especially those with higher end graphics cards) I would HIGHLY suggest upgrading to Windows 10 if you haven't already if you want the BEST graphics experience when Fallout 4 drops.
Let me know what you guys think.
