DeathAdder Halp

just got my deathadder and Qck+ mousemat after i phoned up amazone a month later after the sent me a Microsoft habu which i thot was a deathader (i am a downy)
they said sorry and sent me the proper mouse and i got free delivery :D

but anyways higher the dpi the more accurate so i put i t up to 3500 the max on deathjader its impossible to click on stuffz on desktop so i put the on the fly sensitivity thing at 2 which should make it as sensitive as 700 dpi

my question is for anyone with any knowledge here is using 3500 dpi @ 2 sense in razer driver the same as 700 dpi or does it do the same thing as if you made your windows sense slower and muck up single pixel precision.
