You generally want a sound card with signal-to-noise ratio over 100dB, but the best sound cards are in the 124dB range, which is a significant improvement. Channels - A lot of decent, budget-friendly sound cards typically support 5.1 channel audio, but you can spend a little more to get one that can handle 7.1 surround sound.

High-end sound cards provide as high as 24-bit or even 32-bit audio with a sampling rate as high as 192-kHz or 384-kHz in the latest sound cards. These specifications roughly define the audio quality of the sound card, although there are other factors included such as gold-plated connectors, Electromagnetic-Interference shielding, etc. Sigma does not provide a rating for the amount of assistance provided by the OS system in the Sigma 18-200mm f/3.5-6.3 DC OS HSM C Lens, but 4-stops is the norm for lenses being introduced at this time.
