What games can a 7600gs run?

My eldest lad has passed the old rig i built him for his 8th Birthday down to his 10yr old brother.

It's a althlon xp 3700 dual core with 7600gs and now running windows 7.

My lad plays xbox etc but said he would like some older pc games.

What can this run? Call of duty and battelfield i imagine?

Any info please guys. He wants Shooters etc etc. No sports games.

i still have a blast on mohaa, quake, unreal, revolt, and crimson skies and it will piss them.

Heroes of Might and Magic 3 will run off a gerbil in a wheel powered PC and is an absolute classic.

All Valve games (Half life & Half Life 2, Team Fortress, Portal, Counter-Strike...).
Star Wars
Star Trek Elite Force
The Chronicles of Riddick - Escape from Butcher Bay
X3 & Descent: Freespace [2]
Tom Clancy's Ghost Recon Advanced Warfighter [2]
Tom Clancy's Vegas [2]
Max Payne
Doom III

A few of the titles might give the boy nightmares. I guess I'm a c*nt for including them ;)
