xorg problems, GeForce 7800, Sony Multiscan E400

[commodianus]

My xorg.conf is below, I would appreciate anyone with more experience than I have to make suggestions for changes that may solve my problem. Some games/3d apps work fine, example; tremulous, trem fusion, however, supertux, extreme tux racer, tuxkart etc give me sync out of range on my monitor.

I believe I have set my xorg to my monitor's specifications, however I may be missing something.

Specs here:

Video card is Gefore 7800 (GS)
