It really doesn't? I've always heard since I first started building computers that it did...hmmm Oooo I'm gonna disable the audio in game tonight and see if I notice any difference, if I do notice a difference wouldn't it be the same difference as having a sound card powering the sound?
I don't have the money right now but if I did get some money it probably wouldn't be more than $30, which is about what I bought my stick of ram for but now the price has doubled. Oh and every price quote I say is really doubled as i will have to buy my wife one also so I'm not running the game better than her and having to listen to those comments daily..lol
