You might want to consider an i7-2700K. It is cheaper than the 980 and has a better Passmark score. 11,129 vs 10,299.
Wow! 5 monitors!
I have 4 20" monitors. If I was redoing my system and money wasn't an issue I would probably replace the center 2 with a 30" 2560 x 1600 but in landscape mode. My desk is in the center of the room and I like to see behind it.
