[citation][nom]eklipz330[/nom]there's many out there, the more recent ones pretty much saying onboard sound has gotten so good, human ears cannot differentiate over the marginal .01% that discrete cards offer over them... if you get an audio card, just make sure it has all the dolby and thx certifications and at the very least its own built in amp... otherwise, you wont tell a difference. trust me, a guy whose been disappointed by several audio car purchases, a better pair of headphones would be a better investment.[/citation]
it depends.
onboard is good enough, but once you get passed a certain point, it does make a difference, granted it may be small, but lets say you do get a Sennheiser HD 700 or 800 (2 of the best you can get) you would hear the difference, granted if you just get the cheapest sound cards you can yea, they wont be better than onboard.
