I am going to buy a new mouse because my MS IntelliMouse Explorer 3.0 is old. I am a gamer and will get a nice surface for the mouse. I dont care if it is wireless or not, but must be optical and have atleast 5 buttons. Ive heard nice things about the Razors, but do they have 5 buttons? I dont really care for the new 4.0 IntelliMouse Explorer, but I havent had alot of hands on time. SO I was considering the : MX 500, MX 700, a Razor Boomslang, any other Logitech or MS or Razor you suggest. Id like a high DPI, so please take that into account. Thank you for your help.
