\"Help\" 27\' FullHD (1980х1080) or 29\' Ultrawide 2560x1080

The actual question what to choose,the monitor is 16:9 or 21:9 ??
System ryzen 5 1600+ 6gb gtx 1060
21:9 attracts a width greater immersion in what is happening on the screen in games and films
Pushes the fact that not everywhere and not all have support for 21:9, especially in the serialchik, and I love to see black bars appear on the sides much do they irritate? I heard that there are plugins extend the picture,I don't know how it works, I would like to hear from those who have faced
Well, the main problem is that the video card is weak,would it be enough for 21:9 in games on ultra or at least high?
The rest of the monitors are identical, the matrix ips ,75 Hz, 5ms, etc
