Looks good, I am not worried about the so called CPU "hit". I was running a Phenom II at 3.8, so I am sure it would have been fine on that but I am selling that and now I am running a i7 2600k at 4.6 Ghz (Could do 4.8 with about another ~.05v).
That's crazy how far the Creative lags behind performance wise. The only thing is since I am picking up mine used it doesn't have any of the accessories but whatever. I really am surprised at how few PCIE audio cards there are.
I personally liked the Via interface on my last board, it was a VT1708S and it ran perfectly. Did all the speakers, took Stereo sound and ran it through all my speakers correctly, bass on the larger ones highs on the tv speakers and mids on my logitech speakers. Too bad they are only PCI not PCIE, I figured since PCI is going away soon (at least on Intel boards) more companies would start making PCIE cards.
