A gaming mouse is essential for a PC gamer! Using a gaming mouse instead of a 'normal' mouse can mean the difference between life and death in a game. A gaming mouse gives a better performance due to the high DPI and the adjustable DPI. For example, a 'normal' mouse can only have 1000 DPI while a gaming mouse often has 4000 DPI. Dots per Inch (DPI) measures how sensitive a mouse is and gaming mice are often equipped with specially placed buttons that are programmable and make gaming easier. The (RGB) lighting finishes it off with a unique and cool look. These lights are often also programmable.
