Not sure if this will help but I've just loadeed Far Cry into a 5 year old Toshiba lappy, P4 2.6gb,256mb ram and 64mb onboard video, just to see what happened. It actually plays the game quick enough with all settings on low. It does have a problem with some of the colours though eg, on the first level the sand and the sea are both black :-(
I'm sure that with your spec there will be some games that will run fine. Far cry is quite demanding.
Perhaps some earlier games will run well.
Other members might suggest some.
