Since glories days of Quake 3 are far over and Quake 4 didn't actually rise from the shadow of it's ancestor, ID software made full online, browser based game called Quake Live.
It's core is basically Q3, but some grafix upgraded and some other new game features. It's free game, which is easy to download, easy to install and get playn, where ever you are.
As you create your account it will make statistics, based on you can find battles more suitable for your skill.

So are here any old or present Quake or other hard FPS gamers?
I played Quake 3 ages ago, so now i discovered this, it's fun to shoot from time to time.
