Best QHD Monitors?

[Panel]

I recently made a thread in which I was considering many different options with which to replace my current Dell 3007WFP. One of those options consisted of purchasing dual QHD (2560x1440) displays, and later adding a 3rd display.

In this thread, I want to ask which QHD monitor out there is the best?

I'd want to it to have:

1. Terrific color quality/reproduction/uniformity (for use in design, as well as AutoCAD. This is the MOST IMPORTANT feature for me)

2. A refresh of over 60Hz (though I don't particularly care whether or not it's an insanely high refresh)

3. G-Sync (Don't care much about this, but it would be nice to have on a resolution that's technically outdated now)

4. Curved (This messes with color accuracy, and as far as I know there are no QHD curved monitors. I care the least about this).

Let me know if any of you have any suggestions.

I'd prefer to stay below $500 for this, but will go further is necessary.

Just get one of these and be happy.

I've got the Omen 32 coming, a few people around here advocate for it. I'll leave you my impressions.
