I want to know if I can ypgrade my sounds to a much better quality than I have. Volume is all the way up, and it's only as loud as a typical conversation. I need to crank it. I don't know if it's seperate from the graphics card. Just put a NVidea quadro GTX 550 in and the sound is not much better than it was with the NVidea FX 600. Any and all help will be appreciated.
