Similar to graphics, sound has become a factor of major importance in the PC world. PC users who are avid gamers, collect MP3s or watch DVDs need a good sound card and an equally good sound system.

Let's not forget the undeniable contribution of Creative Labs and Altec Lansing who imposed the 4.2 and 5.1 sound standards for games.
