depending on that, this one would be an option -> LG 34UC79G-B (34", 2560 x 1080 Pixels)
This monitor is more gaming focused. I would strongly advise against working with such a resolution on the web and in the office. Also, a lot of money would go into the speed of the display, which you simply don't need on the web.
Rather buy a 32" monitor with 3840x2160 pixels.
I agree with Crazypif. I use the monitor with a GTX690 and hardly notice any performance differences compared to the previous monitor (was 1920x1080).
