I'll take a stab here..
You didn't say what kind of gaming you do, so that leaves this one really up in the air.
Being that I am a mainly FPS player I stills stay with a wired mouse, I know battery life has come along way and all that. But nothing sucks more than to get in a sniper war on Urban Terror and have your mouse die! So with that in mind, here are a few options. Some I have tired. Others? Well that is up to your googlefu skills.

- The razor series of mice have truly been some of the trend setters when it comes to cramming resolution, buttons and customizable layouts to not only mice but keyboards. However, reviews are mixed and be ready to pay a price for their wares.

- If you don't know logitech, it's time to move out from under your rock and say "Hello Starshine. The earth says Hello" or something to that effect.

I have personally owned the G700 and while it is pretty shweet as a gaming mouse, it was not a fit for me.

- Now this? This beast? This conundrum of parts that looks like a mouse mated with a Borg? This is the gaming mouse I want! It's is one of the most customizable, trick-out, make your fingers do the bionic seahorse mice you will ever find! It does take a bit of getting used to, with all the options available it can be hard to know where to start, but if you want the bang for your buck? You can't go wrong.
