Has anyone upgraded from SBlive Plat. to Audigy 2? Was the difference huge?Seen alot of articles saying this is the one.Unfortunatly Im still loving my Klipsch pro media 400's so I am missing that 5.1,6.1 sound on my gaming machine.I do have on my soyo dragon ultra a SB 5.1 card with Logitech Z-640s,but I still love the SBL plat. with those klipsch,so If the Audigy 2 is way better ,Ill go with what you guys say, not the sites that got a free card. Thanks
