I've had a 34" curved ultrawide (3440x1440) for about a month now, and I love it. For gaming, it's great because my GTX 1080 has no issues with it with the games I play. For design work, having all that extra horizontal real estate is great to tuck away palettes and other extras. And for coding I can have an IDE in 2/3s of the screen and a browser for stupid CSS questions in the other 1/3, and still have that browser at a width that doesn't trigger mobile media queries.
Yes! I've got the Dell Ultrasharp 38 on my desk and it's been wonderful. It runs at 3840 x 1600 and gives me lots of room for text editor, terminals, and web browser, filling my line of sight while I'm working.
