No way, the triple screen set up is superior.
You get more screen for it in return, in GTA5 i can see 120° wich makes first person easy.
Race games and flight games are unplayable in first person mode without triple setup.
The bezel is something you wont notice if you use bezel correction in nvidia option panel.
Its like looking trough a window, you wont notice the frame at all.
Persons who complain about it , didnt experience triple screen long enough to adept, or are prejudiced, and fixated about that.
I as a owner of tripple screen setup am glad i tried it. I also was doubting the bezel thing, but within a few days you wont even notice the bezel anymore.
Like i said, i cant imagine me playing single anymore, especially when playing games like GTA5 first person.
Or F1 first person... With tripple i can see them next to me, without i crash...
