I read a lot of information on the net, but I still couldn't make my mind from those, so I came here for some enlightenment... So, as far as I can understend Vista no longer allows direct hardware access for sound processing. Does this mean that it doesn't make any difference between a on-board sound or a Xi-Fi? From the CPU point of view, NOT from the quality point o view. Second, I own a M2N-SLI Deluxe MoBo, and I found out that the sound was not so great for surround output. I was thinking about getting a off-board sound card, how much of an impact would it make on my performance (under windows xp, for if I am correct, it wont impact at all on vista) and would the sound quility improve seriously? THX!!
