That's about $1000, and it buys you a 32" 4K OLED panel with a high refresh rate, better than anything the Mac has. That's the kind of monitor you would pair with a gaming rig though, and probably overkill for the kind of office use the Mac is intended for.
If I were buying a display for work (which is to say, mostly programming), my choice would probably be the £600 BenQ RD280UG — a 28" 3840x2560 display, which is 4k vertically enlarged to a 3:2 ratio.
