Almost done buying components for my first build, but I want to make sure I'm making the right choices on what's left.

###Build Help/Ready:

Have you read the sidebar and rules? (Please do)

Yes.

What is your intended use for this build? The more details the better.

I would like to play games on max settings and also stream.

If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings)

I have consoles, so this will be my first legit pc that can play AAA games on. I'm not 100% sure what I want, but I want to be getting my money's worth and have everything look nice.

What is your budget (ballpark is okay)?

I think I'm at $2,000 with what I've selected so far, so that's fine.

In what country are you purchasing your parts?

US

Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!).

Provide any additional details you wish below.

Since I've already bought most of it I only need help with the last couple of decisions. Most important one I think is the graphics card. Is the 1080 worth it or should I just keep watching 1070s until they go back to normal price? Second thing is the cpu cooler. I know that I want a liquid one, but I'm not sure what I need. I have just been looking at what other people have been pairing. Third is do I need the extra fans? Like I said this is my first ever build attempt so I don't know if I need to replace the fans that come with the case since they're more quiet orrr?

Open to complete changes in the parts that I have left. Just need a little advice. Thanks in advance.
