I don't see why not. As long as you have enough video cards to provide signals to the screens that is.
I have a pair of Viewsonic's now, one E790B and one VG175, both are very nice.
Go for the ultimate... a wall of screens, or better yet, make a full arch, 160¡ of coverage, tow high 😀. Make the peecee people drool when they see all that attached to one computer.
