I have the following motherboard http://www.newegg.com/app/view...=13-127-178&DEPA=0 and was wondering If I would be able to hear a significant difference in sound between the onboard sound I have which is AC-97 Codec and the 24 bit audio that I would get from an Audigy 2 ZS, I'm not good with sound and would appreciate some opinions because they have an audigy 2 on sale at my local Best buy for $49.99.
