I am using a Dell Studio XPS 8100 machine and i have specially bought this desktop for gaming purpose. I was playing Battlefield 2 on this system and the game does not sounds better. This machine has a Creative Sound Blaster X-Fi Xtreme Audio PCI Express still it is not enough to get the clear sound while playing game on it. I am getting very much popping and crackling on this game. Same kind of problem happens while playing the Day of Defeat.
