yeah i would think with 2x gtx titans you probobly have a relative budget for monitors
.. if thats the case you can certainly pop for 3x of the 2560x1440 or x 1600 monitors. you can go big box like Dell, or you can go the alternative koreans and get a catleap / shimian or similar. but do keep in mind the korean monitors often have a pretty big bezel, and it can be hard to safely remove!
Now if you don't mind sticking with the 1080 resolution but you still want to use all that horsepower, what about going 3d? Also this baby has on HELLA-TINY Bezel:
Samsung S27A950D
they seem to be pretty hard to find, but man are they sweet.
my other recommend if you want to stick with 1080, don't need 3d, but still want a large and amazing panel is the AOC 27 I2757FH.
Its a bestbuy Exclusive, but all reviews on it are great, and the bezel is only around 12mm counting the interior border.
