In our last gaming mice showdown, the Logitech MX518 came on top of both the Razer Diamondback and Razer Viper. Since then however, new products have been released by both companies, and we are glad to inform you we have had several weeks to test them and report back to you. The contenders: the Logitech G5 and the Razer Copperhead, both considered the companies' flagship gaming products, both corded mice, and both tracking at an impressive 2000dpi. This is a head-to-head showdown to see which company has the best gaming mouse currently available.
