Since you want to get a better graphics card, I'm assuming that you are wanting to play video games. If so, I would definitely recommend upgrading the video card. If you don't play video games, you really don't need a video card. Usually, the sound on motherboards are perfectly fine, in my experience. On the other hand, you could just keep the video card that you already have listed. To answer that question there are a few questions that need to be answered. First, how much do you play video games? Second, what resolution do you game at?
