Since you have it, try it. Obviously, a card of that price range and vintage is not going to give you the best quality sound, but I bet it would beat onboard sound. As for the MSI portion of your question, I'm not going to delve too deeply into that, because it would serve no purpose. I probably should have omitted my previous comment for the same reason, but my dislike for MSI runs too deep for me to keep silent some times.
When you said that you liked the layout of the board, exactly what did you mean...that you liked it's appearance better, or that it had some functionality that you didn't find elsewhere?
