I'm ready to upgrade my soundcard but can't decide which one of these to get. I use my computer for listening to music while I surf and also for gaming. I plan on drilling a small hole in the wall behind my computer to run audio and ethernet cables to the living room where my HT is located. I have read a lot of good things about both cards but nobody has compared the two yet. All reviews have talked about the previous SB Live Platinum, not the new Audigy. Is the new Audigy Platinum EX worth the extra $100? P.S. I currently have a TB Montego with an Aureal chipset running in Windows XP. Since Aureal was bought out by Creative I doubt there will be any XP drivers released.
