I'm hoping to build a pc sometime this year. I would like good sound quality because I will be gaming on it and listening to music. Would it be worth it buy a sub $100 sound card? Maybe something like this http://www.turtlebeach.com/products/sound-cards/riviera.aspx . I'm thinking about getting an amd 880g motherboard. I have a turtle beach earforce x1 headset. I also plan on buying a set of 2.1 speakers along with the computer.
