yes you need a soundcard because the p5q pro has no onboard sound
Maybe you should take a second look at it. http://www.newegg.com/Product/Product.aspx?Item=N82E16813131299
@glenngjp The P5Q Pro does have onboard sound. Onboard sound is pretty much standard in all motherboards now. You shouldn't need an additional sound card to run those speakers. Onboard has definitely improved over the past couple of years.
