Need Advice for First GPU Purchase

[Gingy]

I've recently built my first computer and I've decided to upgrade it by adding a GPU. After much consideration I've decided that I'm going to go with the Nitro+ 8GB RX 480. However, I'm a complete noob when it comes to the practical application of GPUs and I would really appreciate some advice with a few different things: 

 

1. Operating System: I've been using Windows 7 for quite a few years now and have resisted switching to Windows 10. However, with a new GPU is there any advantage in upgrading to 10? (I'm not really willing to try Linux even if it might be better in some regards, sorry).
2. Drivers/BIOS: I've found plenty of tutorials about the actual installation of a graphics card, but very little in regards to the Drivers and BIOS required for "setting up" or installing a new card into a system. This makes me a little nervous because I've heard a few bad things about AMD drivers and I don't really feel like I know what I'm doing. If someone could share some instructions to help me out with GPU drivers or maybe even the RX 480 specifically it would be much appreciated.
3. Is this even the right card for me? I've put a fair amount of research into this, but its more than possible that I've overlooked something important. My intention is to play a lot of games, both old titles and new AAA ones. I have 3 1920x1080 monitors with DVI and HDMI inputs and I hope to possibly get into VR in the future. I'm trying to find a card that is decent on a budget and the Nitro+ would be about $280USD for me. So with my current build (http://pcpartpicker.com/list/9fCDqk) would the 8GB 480 make sense?

And that's all I can think of for the time being. The community here has always been helpful and I have gotten some good advice in the past. Any more help here would be amazing! I'm really excited to finally pull the trigger on this and start gaming in style.

 

Edit: I'm also considering going with the 8GB Nitro+ 470 which would be about $40 cheaper right now. Any thoughts on that as well?

if you build that computer recently. why you didn't choose to build a skylake (6 gen) instead of a 4 gen intel core CPU.

 

Anyways my real question is what are you aiming for. example: i'm aim for playing games a 1080p 144FPS at ultra settings.

Bought most of the parts (CPU) when they were cheapest and it wasn't until ~2 months ago that I had everything I needed to actually build it. Otherwise yeah, something like a 6600 would have been better. Anyways, my goal is to hit at least 60fps at 1080p and ultra or high settings for modern titles.

The Rx480 for AMD or the GTX 1060 6GB for the green team.

 

but if you want more (i dont know if can cause bottleneck) the GTX 1070 is for you.

The 480 will be a better option over the 470 since you are using a 3 monitor setup, there will be a lot of pixels to drive over the 3 monitors
