How important is a good mouse in FPS games? (anyone heard of g400?)

Generally optical is better, however laser comes and goes with each generation of mice.
Typically speaking a 1800 dpi mouse from the likes of Logitech, Razer, Steelseries etc, will be sufficient.

The thing to look for is how many side buttons does it have, is it ambidextrous (if you are left handed), do you NEED wireless?, does it have weight plates you can put inside, and MOST importantly does it have it's own button remapping software <---this is huge.

For a nice mouse that's got a few side buttons, the Razer Deathadder (first version will be cheapest) is a nice upgrade. Razer make a free program called Synpase that lets you reconfigure the entire mouse.

Word of warning about Razer and Synapse. Some users have had their mice rendered useless by the software. It's rare, and seems to affect only certain models. There are ways to fix it, but it can be quite frustrating if it happens to you. Personally I have never had an issue but I've only updated my mouse firmware once since I got it about 2 years back.

Off topic. Saying your name outloud is fun.

I'd stay away from the Cyborg stuff.

Hope that helped.

I love my R.A.T. 7. The customization options are great, you can really do a lot to adjust it to fir your hand, and the precision aim button is fantastic. You can change the size and weight of it easily.

One thing I would advise, is staying away from wireless. While they seem convenient, you don't want signal interference or battery life to be an issue in the middle of a fight.

My two cents.

Don't get wireless, they can sometimes have input latency. Plus wired is cheaper.
Don't get Logitech, their quality has really suffered the last decade, I won't even buy Logitech headsets. I prefer Razor myself but lots of good brands.
