well it depends what you mean. if you have a really decent since televsion (and quality), and a good decoder for your home theatre system, then the experience of watching a DVD in your lounge room (?) would be much better than anything your 17" monitor + sound system could muster up. However, i think having a nice 5.1 system for your comp is a nice thing to have, especially for gaming. In short, it really depends what you are comparing between the two systems. The PC ones, with your sound card, probably have better overall audio quality.
