Those not yet on an ultrawide should most likely wait a bit as the current proper options are soo darn expensive.
Ive had 3 ultra wides now, the AOC q2963pm a decent monitor though with a touch to much blur, a dell u3415w which had horrible pixel transition in some areas(why ohh good why didnt i just listen to the tftcentrel review) and my current cheapo lg29um57 OCed to 75hz but lacks proper inputs(i hate HDMI) but it is pixel perfect and almost no bleed(no yellow ips glow and only a little magenta'ish during the night with very dark/pitch black scenes which is totally overlookable).
Problem with ultrawide for me is once you tried it, and if you like it ofcourse, you cannot go back to 16:9. It just feels so narrow.
