Definetly get a sound card, the difference between AC97 (I assume that's what it has) and TBSC or audigy is like night and day. Get the audigy if you mostly just play games. The TBSC is decent at games, but it's much better for listening to MP3's. Also to tell the difference between the two you need to have pretty good speakers, and even then it's kinda hard to tell. I would get whatever one you can find that's cheaper.
(I found a few online articles that said that in essence, the difference between SB live 5.1 and audigy was the firewire ; the chip is in essence the same.) If nothing else, that particular card has been working quite well, and on a 2 speaker / bass setup, the improvement in sound quality from AC97 sound was phenomenal! -- Paul
Yeah, I have 3 audigy OEMs. They are the same thing as the Gamer/Mp3+ Audigys, except they have no bundle, and I think only the Audigy Platinum has those STUPID gold-plated connectors.
And I wouldn't go for the SBLive! if i were you. I had one, it sounded great in one box, but caused stability problems like crazy for another box. Lol, it was pretty funny, box kept crashing, no matter how much hardware I replaced. Never thought it would be the sound card...
