hey guys im contemplating on buying a diamond back razer mouse, but there 75 bucks after tax and i have to buy a new PSU and i want to buy a DS so im wondering if they really do make that much of a difference, its def nice looking and will go with my set up but im really comfortable with my intelli mouse but spec wise i know nothing of it, does having 1600 dpi or whatever really make that much of a difference in games? does it improve frames some how?
