Triple Monitor Setup

Through a series of non-sequiter events, I currently have three monitors and an open question on how to configure my setup:

Dell U2713HM (27” IPS 60 hz)
Acer XB270HU (27” IPS 144 hz G-Sync)
Dell U3415W (34” IPS 60 hz curved)

How would you personally make use of these? My initial thought is the two 27” side-by-side with the 34” ultra-wide situated above them. Any other ideas welcome.

34 ultra wide in landscape, with the 27” panels beside it in portrait mode.

Sell the 3415 and get another 2713 and have the Acer in the middle, if you are a gamer.
Otherwise I would do 34 in the middle with the 27's on either side in landscape since they are the same height as the 34.

Sell all three and get an Acer X27
