I have just bought a new system and it comes with realtek ac 97 sound. My
old computer has an audigy(1) would I be better off putting this in or is
the real tek just as good (i think it comes on the motherboard a8v Asus)
What specific uses (in audio terms, not applications)?
For example, digital or analog output?
Gaming or general use?
For most uses the two will be similar, the Audigy a little
better for analog out. Perhaps more importantly it will
have better filter circuitry which cuts down on system noise
on analog I/O. If you're just listening to windows' midi
sounds on small computer speakers it wouldn't make much
difference either way, except the audigy will help with game
framerates as already mentioned by Derek... though that's
with surround effects, in a 2-dimensional-audio game
(regardless of whether game is 2D or 3D) there should be
little to no difference.
