Graphics cards aren't the greatest. Radeon 6790 and Radeon 7750. It would have been nice to get the same model and put them in crossfire, but I bought them a year apart.
could always get another 7750, they are fairly cheap now-a-days
But that is definitely enough to get triple monitors running fine. You use to the gaps in between the monitors yet?
The gaps don't bother me too much other than when I try to play something across all of them. I don't have bezel adjustment setup on them, so that's a little annoying.
