Okay, thanks for all the reply's it makes a lot more sense to me now.
And for people who ask why i need 4 screens
I have 4 right now to my Desktop, and i use them all everyday.
It could probably be replaced by 3 widescreens but i can't go down in monitors.
I am totally in love with Lewis (Unbox Therapy) desk setup (i know he uses Mac Pro).
