Dual screen for work, yes. Dual screen for gaming, no (you'll have a split right in the middle of your setup, which would be terrible for gaming)
I used to be the biggest proponent of 3 screen gaming, but it's become such a hassle now, and you gotta have a monster setup. I say get an ultrawide 3440x1440p screen and just go with that. My 34" is perfect. You still need 2 high end GPUs to get all ultra, 60fps, but it is definitely manageable. I'm done with 3 screen gaming. Ultrawide is were it's at. Since my shyt is 34" I still get the peripheral advantage too. As somebody that was a cheer leader for 3 screen gaming for half a decade, I'm glad to be out of it. Ultrawide 1440p is where it's at. More games support it, there's no black bars in you field of view and it takes less horsepower (it's 3K, instead of 6K if you go 1440p).
