Utilizing Speakers

http://www.newegg.com/Product/Product.aspx?Item=N82E16836116025

I have a Creative Inspire 5.1 surround sound speakers, but I don't have a audio card. Meaning, I am only using the motherboard's built in sound card.

So, I was wondering what would be the best sound card (quality and money wise). I want it to be cheap in price, but I want it to work well while playing game like Call of Duty, Dead Space, Company of Heroes, and Crysis.

Cheap and good don't really go together well with sound cards. I'd try this cheap X-fi or audigy card by Creative.
