The new X-Gamer 5.1 comes with Unreal Tourny and Deus Ex and 1 or 2 others...I don't much care for software bundles usually, but that's a pretty good one.
In my opinion the Aureal SuperQuad2500 is the best soundcard that has been made so far. Unfortuantely without driver support it's not going to be much good in the future...personnally I'd hang on to it for a while if you already have one, try and wait out a "new" soundcard from creative.
The SBLive! Value, regular, X-Gmaer, MP3+, Platinum, X-Gamer 5.1, MP3+ 5.1 and Platinum 5.1 all use the exact same audio chip (as do any non north american versions I've missed) there are 4 or more revisions of the board, but they all have the same chip, just different connectors, bundles, and little extras like that...
Hopefully they will actually come one with a new soundcard next year as they seem to be on a 1 year cycle...hopefully next year won't be a revision of the Emu10k1...
(98 was the release of the SBlive! and value, 99 was the X-gamer,mp3+,platinum, and now the 5.1 series)
