Do I need a sound card ?

[Rohiric]

If I was going to buy this headset http://www.aria.co.uk/Products/Peripherals/Speakers+%26amp%3B+Headsets/Headphones+%26amp%3B+Headsets/Cooler+Master+CM+Storm+Sirus+5.1+Surround+Sound+He adset+?productId=47251 would it also be a good idea to get a sound card with it or will that not make a difference ?

Those particular Headsets are USB. That means they have their own built in soundcard. Its not as good as a dedicated soundcard, but better than onboard.

Even if you bought a soundcard, the headet would still use its own, sooooo....... You do not need a sound card. :)
