I am not sure if this is the right forum, so i appologize for that, but I was wondering about Razer mice. I was thinking about getting a razer vs say the MX518 for gaming... I was wondering if anyone could tell me the differences between the copperhead and the diamondback... I know the copperhead has better dpi (2000 vs. 1600) but i really dont know what that means and if that makes a difference or what... Any help is appreciated.
