Lets face it this monitor is for business and not gaming.. Dell sells tons of monitors.. almost every office I have been had almost all double Dell's on each desk..
While it is their "professional" line the fact that it has a 6ms response panel means it would be good gaming panel as well. It's the exact same response as my 27" Dell 1440p.
About the only thing I will say negative about Dell's upper tier IPS panels is that they do not overclock well. I got mine up to 80Hz but there was severe stuttering problems with V-sync on locking FPS at 80 in games. I never had that problem on my cheap LG-made 27" Crossover 1440p knock off (Apple Thunderbolt reject).
You seem to know the scope since using one.. to pricey for me.. my acer for gaming.. tho big size.. over a grand no way..
aaaahhh yeah.. mine is 27 acer.. sits to my left.. on a large leaning forward art table.. with a 40 visio about five feet beyond.. both running at the same time.. mute one off with pandora blasting through the speakers..l
