Widescreen monitor - flat or curved

[Mallers]

Hi,
Currently I have 2 monitors side by side, dell u2715h, resolution 2,560 * 1,440. I have my desktop and games set to 5,120 * 1,440, run off a single nvidia 980TI
Im considering replacing with a single monitor with same resolution to remove the break between monitors right in the middle of the screen.
Although i liked the idea of curved monitors, im concerned given the size of something equitable to what i have now that the curve on the edge is going to take too much space off my desk, and that i might be better off with a flatscreen 5,120 * 1,440
So, does anyone know of a flatscreen that would be suitable? After same sort of resolution, to be used for some call of duty FPS games, mostly Total War warhammer strategy and general home pc use. Is a single monitor annoying to use when opening multiple windows (my current setup has internet defaults to fill right hand screen, email does left)?
Or, is there any special reason why a curved monitor should be best? Its desk based so im fairly close to my screens, im not bothered about full immersion, just losing space around the curved edges

Personally I think curved screens are pretty pointless on or below a 27" screen. After 27" they start to get useful. A flat 34" monitor looks like the edges are too far away!
Regards resolution, well there aren't many choices at that resolution and all of them are curved. They are 49" monitors. But even simple maths tells you that while a 49" monitor looks huge it's actually smaller than the two you have.
