Experience excellent sound quality not always rated by having expensive speakers. Sound cards also hold an important role in this matter. It will be no good if you use expensive speakers, but still use onboard audio device. My computer have onboard sound card which is support 7.1 audio system, but I still prefer to have Creative sound card even tough my Creative only support 5.1 audio system. I choose this card because it can produce excellent sound quality. Also, this card has EAX audio technology and CMSS technology. EAX technology redefines my gaming and music experience with true-to-life 5.1 audio and different environment settings for realistic and immersive 3D positional audio experience. And CMSS technology have the capability to ® up mixes ordinary stereo sources (CDs, VCDs, WAVs or MP3s) to virtual 5.1 channels. As a result, games, movies, and music that played can produce high quality sound to bring satisfaction. I bought this card only $30. Not too expensive compare to others sound cards that offer same features. Of course, if you have more budgets, you can have high end Creative products which it cost above $100, since mine is only middle end category. But with only $30, I can have better quality surround audio for games, movies and music.
