I have just bought a G7 and can't praise it enough. I didn't think the mouse you use would make such a big difference in games.
Prior to last week my highest scores on F.E.A.R were around 170-200, since playing with this mouse i am regularly hitting 350-450!!!!!
Well worth the money and you can easily switch down the sensitivity for windows.
