What are the differences between ALC888, ALC889 and ALC889A audio chipsets?

[boren]

I'm trying to decide between two boards - the GA-P55A-UD3 with ALC888 and the GA-P55A-UD3R with ALC889. Are the differences significant enough to be audible or to offer useful functionality? If not, then I'll probably just get the cheaper board.

According to this comparison there are measurable differences, but it still doesn't tell me much about the real life differences. Just that the ALC889A (same as ALC889?) gets better tests results than the ALC888.

Thanks in advance!

 Obviously you sound like your looking for some good audio quality here, and  I maybe way off, but honestly to me, any MB crappy audio chipsets CANNOT really beat a good old "quality" separate "Sound Card" period. Especially, these stoopid audio MB-chips that tout "HD" audio like you can only get that, or even hear it with thier respective MB's. ?
 It's basically like comparing Graphics Video-cards with "onboard" MB-graphics-chips. ?  -yipee!
 The trouble lately, is that the "really" good Audio cards are almost as much $$$ as the freekin' MB's today ?!
