Quite a few flat out stupid comments here. First of all - the curve ain't that big. Second - you're not likely to spread out a chart over an entire wide screen anyway. And even if - the curve won't be a problem.
I use a 49" Dell. Works great for me. That said - you're not getting any more screen estate than you would using 2 x 27" 4K screens. So unless you mind the bezel in the middle (I do!), you can save yourself some money.
Since I run this off a laptop - I'm also happy to reduce the number of cables/inputs.
