You'd need at least 2 cards to run it (One dual-headed card using both outputs and a second using one port), and for a game like Crysis, they'd better both be at least 8800s. That video splitter you linked would just send the same exact picture to all of the monitors. If that's what you want, great, but I think you're wanting to have the picture span all 3 screens. This all assumes that the game actually supports it, which afaik, it doesn't.
