I was wondering what the best PC 5.1 surround system is? I made a post earlier about which I should upgrade to - speakers or a vid. card, so I'm doing research on the two topics. Everything I've read points to the Logitech Z-680 speakers (I'd upgrade to the Creative Megaworks 6.1, but there isn't a whole lot of stuff that supports 6. 1 speakers, and I heard that some games that don't sound funny - so I figure why waste the extra money). Is this assumption correct?
