Sonic Firefly 302 Plus. Using the Firefly is one way to avoid the dual sound card crash that Windows suffers from (still might but I havent had it happen ever). This way the game uses your primary sound card for game sounds and the music can play over the Firefly. For a few bucks more (like $50 US) you can hook up a condenser mic with +48V phantom power. Crystal clear sound both ways but it isnt a gaming sound card nor is it really great for music so if your an audiophile you might not think its that hot but it sounds great to me. It will work for games too but there is no 3D position handling. None. Dont expect to play AH and find tanks with it. Works with XP Vista Windows 7 and Mac and you can usually find them in music shops. Requires an IEEE 1394 port. Primary benefit is ZERO lag.
