I have this set of speakers and honestly for the price, they're pretty good. If bass is your thing then you'll love them, at times I find they can be a bit bass heavy and some of the detail is lost when listening to music and films, however for gaming I've found them to be perfectly adequate; you just have to play around with the bass levels a bit As for use with a sound card I can't say, but they're a pretty good bang for buck set
