Just a few things:
1) L4D is the most awesome game Valve have ever made!
2) Always close doors! (They block zombies and allow survivors to spawn)
3) FFS crouch in the doorways so you don't get capped in the ass
Here's a few screenshots of me and the "Joker" W0rf0x:

The game runs smoothly on my 8800GT at full settings (Not 16QxCSAA because it crashes) at a capped 75FPS no probs but I turned down some of the AA and Anstropic because the flashlight soaks up 40 FPS on it own
