Counter Strike is world famous dude, named the best online-action game many times over, it's getting on a bit now though, they recently released CS:Suurce, which has updated graphics and physics, but for your system I would reccommend CS 1.6.
You can get it a few ways, firstly there's steam : http://www.steampowered.com/v/index.php Valve's online game delivery service, Counter strike is $9.95 there.
Alternatively you can try to find it in a store, although you may not be able to find it brand new
