New build in a couple weeks need help with some parts

[Rathalos]

Already asked basically this but several things have changed so I need to revisit the whole thing.

Only things that are set in stone:
Ryzen 1600
This monitor: https://www.newegg.com/Product/Product.aspx?Item=N82E16824014578
NZXT S340 Elite case
This is on a $2000 or less budget, please keep that in mind with your suggestions. What I need help with is: GPU, mobo, RAM, keyboard, and any advice you're willing to give for this build. I know what I'm doing when it comes to putting it together but I'm really not sure what to do with the gpu for 2k and the mobi is kinda a toss-up

Is the 1080 the best option for 1440p?

Nope with your montor the Vega 64 would be but its bit high priced. It puts you out beyond your price so will require cuts somewhere. Here it is with a B350.
