It takes a little time to work up to it. I'm there now, but it took me a while. I have to turn it dow when I play BF2 or I get dizzy :S. I usually run it between 7 and 6 when playing, but I will pull it down to 1 or 2 when sniping. I tried driving with the sensitivity all the way up... I don't plan on trying THAT again anytime soon.
