looking to put a new sound card in my computer. i have a dell dimension c521 ,windows vista, brisbane 5600 2.9 processor, 4 gb of ram, 5570 radeon vid card,500 gb hard drive (not sure if need that info but its there). im not sure on what sound card to be looking for or if it even matters what kind i get but right now my issue is, i want to have my ventrilo chat going through my head set i got now and my game sound going through my main speakers. i was told i had to get a new sound card to do this even though i had it working on this sound card i have now some then just messed up and i cant fix it. if i can get help on fixing this that would be fine unless i need to upgrade the sound card that wont be a problem either any help would be good. also the speakers im planning on switching to is some sort of coby speakers i believe is the name its just 2 speakers with a subwoofer added to it if this helps any.
