Entirely yourself, if i had the money i'd get the logitech g15, very nice keyboard version 1 is a little bigger and the lcd screen can be moved apparently, version 2 is more compact and the buttons are orange. But if you don't want to spend 70 dollars then any keyboard is fine, it will make little difference to gaming, the mouse is more important. I have 2 razer diamondbacks and love them, good for left or right handers.
