Is the new set of Dll good for a 9800 GTX ?

[Oktoberfest]

Well here are my details :

19" flat screen. I run the game at the max definition allowed IN the game (1280 x 960 I think it is. I'm in the office so can't check).

I will test your advices tonight and tell you if that improved my game.

I also need to get the latest dlls. Can someone give me a direct link from here. I've seen a post about them in the forum but not sure anymore which version work the best.

Thanx.
