Ultrawide recommendations

[Sianlang]

Hi all i am thinking of getting an ultrawide display to replace my current 2x 27" 1440P on a GTX 1070 (would the 1070 be able to drive this resolution 3840x1600?), i have rounded up 3 models below which is selling at newegg. 

- LG 38CB99-W $799 - LG 38UC99-W $899 - Dell U3818DW $1119   Hope to seek some opinions on which is a better buy.

What about this one  ?

i went to retail store and compared 34" with 2560x1080 and 38" with 3840x1600 and felt the latter is more similar to my current setup of 2x 27" 2560x1440, thats why did not consider them.
