I just bought a new eMachines computer equipped with AC'97 Audio and crappy speakers. The sound pretty much sucks. If I purchase some new, good speakers with a subwoofer (I'm currently looking into purchasing the Creative Labs Inspire T2900) will the sound be any better? Or is a new soundcard necessary? I'm trying to avoid spending alot, but I watch DVD's and listen to MP3's on this computer, and it's simply just not enjoyable with the sound being produced now.
