I've been looking on IBuyPower.com lately for a computer as they seem to pretty good. When it comes to sound cards, there's this option, then there's actual sound cards, which run $70 more and up. For now, I'm only going to be wanting a two speaker system with a subwoofer to it. The one they have listed on their site is a 600W PMPO 3 PCS Super Bass Subwoofer Speaker System. Would the onboard sound be fine with a speaker setup like this? What if I wanted to go with a speaker setup such as these Cyber Acoustics, would the onboard sound still suffice? EDIT: Thought I might add that the majority of my sounds are going to be MP3s. I rarely, if ever play any games. And when I am playing games, it's just the useless internet Shockwave games.
