I play CD's on my PC,but the sound is not very good. I want to improve the sound,so it sounds more like a stereo. What do I need to buy for my PC to get better sound?
well depends on your budget. Right now the x-fi line of soundcards are the best, they range from like 70 to about 350, depending on model. However, unless you have really nice speakers, expensive soundcards won't do much.
