Gearheads of War

I remember reading, a long time ago, about how the size of a TV (or display) can affect your reaction time/speed in a video game.  It kind of makes sense; if you have a big picture, the space between objects appears larger, so your mind calculates things as if there may be more time to react.  Granted, in Gears, A LOT of stuff happens toe-to-toe, so it might not be much of an issue, but I'm wondering what size TV do most people play on?  If the likes of Zoso, Really Doe, Machete, and countless others, play on 14" TVs, then I'm definitely heading out to Best Buy before Friday!  As the ladies say, "Big isn't always better."  (At least that's what they tell me.)
