So the mouse I'm gonna get is 5600 dpi but at my cousins he had 8600 dpi and i controlled it nicely and loved it i dont like flashy mouses like the rats i just want a mouse that can game that i feel comfortable with.
You can control the DPI of most mice nowadays. It doesn't have to be some mega expensive model. Even $15 mice would have this option. Just check on the manufacturer's website what DPI supports and if it has a switch to change the DPI settings.
