I purchaced an Asus P5B motherboard that has 8 channel capability. It all plug ins for all speakers and a sub. I put a computer together which is working out fine after me having a few problems with it (naturally).I dont happen to have a decent 5 piece speaker setup yet so I just plugged in a cehap pair temporaritly. Is this board supposed to mean I dont need to get an audio card? Wouldn't an audio card have the same ports for speakers that I already have? Please inform me about how I should handle this.
