Is everyone with the 7.1 surround add-in card just hooking it up to their Home theater receiver, or are there any actual desktop 5.1/7/1 speaker systems out there? The only one I found is the Logitech Z906 5.1 Surround Sound Speaker System. I think I could connect that via the line outs on the surround card.
 
Curious what everyone else is using hooked up to their surround card??
