The /. writeup sounds like audiophile wank to me. I would be surprised if this Soundblaster could justify its price in a proper double blind study on real world data (music, games, movies, etc...) vs. the built in audio on your mobo.
It doesn't help that the squeeze is really coming from both sides: On the low end, the performance of onboard audio has improved(SNR may still make the golden-eared cringe; but horrors of the old days are mostly banished, so adequate performance, usually with fairly well behaved default drivers, is rarely a problem).
On the high end, odds are good that the user already has a preferred DAC and amplifier which will skip the cheap and electrically noisy PC entirely. Even fairly nasty onboard sound often has digital out, and with HDMI and displayport including audio support, so do most graphics cards, even integrated GPUs.
Unless you are trying to drive a touchy and analog only device, maybe a nice pair of headphones or an older amplifier or receiver, there just isn't an obvious need for what creative is selling.
