I am almost done with my HTPC, and my future plans included eventually getting a nice Onkyo Surround Sound system that would the HTPC would hook to......however, these surround sound receivers are very expensive and then it dawned on me.....since my motherboard has built in 7.1 surround sound......why couldn't I just buy a set of surround sound speakers for the PC, and use those instead of having to go into a seperate receiver? Would this be a much more cost effective, yet good results way to go?
