Your much better off getting the Logitech G700 or G700s if your going for a logitech gaming mouse.
They frequently go on sale, and I've seen them as low as $42.50 on Amazon new in the past.
Significantly better sensor, better ergonomics, some more buttons if you want them, Wireless or Wired, Rechargable AA (Runs fine of the cable if you somehow kill the battery, its also replacable by any similar stat recharable AA. I've literally seen one get accidently run over and the guy still uses it.
(Just note if for some reason you need to quickly put a non-recharable AA in it, be aware you can cause damage if you plug the USB in.)
The G700s is by far the best sub $80 gaming mouse I've ever purchased.
Also your not using the standard North American 101-104 key keyboard, for us, Crit Dive by default is " I ", as in Indigo.
