The wavetable cards give much better sound fidelity than the FM boards. Make sure that the sound card you decide on is compatible with the industry standard, Creative Labs SoundBlaster. You will also need either speakers or headphones to plug into the card to hear the sound. Speakers will need to have a built in amplifier and should be shielded so they will not interfere with your monitor's picture quality. Some speaker systems come with a subwoofer that enhances the lower end of a machine's audio spectrum.
Games are great with that extra sound.
Also, if you would rather the computer environment be a quiet environment, be sure to purchase good quality headphones so the sound can only be heard by the computer user.
