Best 4k monitor for colour grading & gaming

[Pesch]

Hey guys I'm having trouble deciding on what 4k monitor to get for myself. I need something that I can colour grade as professionally as possible on, whilst still being okay for gaming in games like Overwatch (not on a pro level).
My budget is under $1500 AUD. This monitor will mostly be used for gaming and video editing.

I'm currently looking at these:

What do you guys think?

 

Thanks for any advice!

First off, get an IPS display for professional work.

Also, do you have an AMD or a Nvidia graphics card? you might enjoy G-sync/Free-sync.

I have a Nivdia 980 and I'd like to get G sync if possible however, accurate colour is more important to me.
