I have that Dell monitor, and i must say that i absolutely love it. Being that my primary use for it is also gaming, the added width of the display gives you a very cinematic experience. For shooters it is absolutely amazing. Do wish that i could figure out how to get skyrim to work properly with it...But games like battlefield are awesome. Games like diablo 3 and path of exile are a little bit wasted on this monitor, but the added view does offer a few advantages over a standard 16:9.
The dell 29" ultrawide overall is an awesome monitor, especially compared to its competition, as the stand is awesome like every other dell ultrasharp monitor, and the usb hub built in is an added bonus.
If you haven't already bought a monitor, my recommendation is get this Dell monitor
