Audigy 2 is an awesome card, especially with the extigy deck, however, the Hercules gamesurround 7.1 or herculues digifire 7.1 card are MUCH cheaper and can achieve 7.1 surround instead of 6.1
i have a audigy and its a great sound card. the audigy2 is pretty much the same thing but i think it has a few extra stuff like a remote or something like that but over all its genreally the same as the 1st one
