If you use SSRC (or similar) with KS/ASIO for 44.1k content, the SQ difference between the Revo and A2 isn't *that* great. Especially not through your average set of PC speakers. I noticed a bigger difference going from A1=>A2, to be honest. If you're a gamer, the A2 is an easy choice, IMHO; If you don't game much, the Chaintech AV-710 is a great buy and a good, budget alternative to the Revo.
I've had no major problems with Creative software (went from SBLive!=>A1P=>A2), but then I always just did the "drivers only" installation. Their application suite is pretty ass-tastic. The M-Audio software has a few bugs but is far more flexible if you use your PC with a decent AV rig and/or headphone setup.
I would say that the difference in SQ between the A2 and the Revo is not enough to offset the gaming performance and price gap unless you have higher-end speakers/cans. Personally, it was worth it (I use a modest B&W/NAD setup or Senn HD600s + amp), but I'm not a serious gamer. The Revo bests most <$500 receivers in terms of analogue output quality IMHO, but on the grand scale of things it is still not that great if you're really serious about music listening/production.
