Not at all necessary no, would be hella nice? FUCKYEAH!
I play on a single 32" and use my hatswitch on my G13 to look around, it's quite fluid. But with an xbox controller you have the use of an analogue stick for that. Works well either way. Though I can imagine what 3 screens and TrackIR would bring to the game.
*Granted, I have a second screen which I use, but that's purely to make notes and so forth.
