Okay so I've got my second monitor, and now I just can't help but think how cool it would be to finish it off with a third... I mean not right now, but maybe over the next year I might get another one. The benefits of a third would be truley great - read documents on one, do work in the middle, and have distractions on the right 
But it seems to bring about a lot of complications?
I'd need two graphics cards? Then I'd need a motherboard that either supports ATI Xfire or nVidia SLI? And then those two cards would have to be the same card?
Or are there other ways of using a third monitor?
