I want to build powerful desktop with triple monitor setup. I have one Dell UltraSharp U2713HM (27 inches, 2560x1440) and I was thinking about getting two more. Would it be possible to have those three working with Ubuntu (Kubuntu) on any graphics card out there today? What is the best option if it comes to choosing particular model? Should I use proprietary drivers or some open sourced ones?
I am not a gamer. I mostly develop on my machines and running some computational tasks, but I would rather like to spend some more money and have setup where I don't see any lagging.
