I am running a set of Logitech Z5500 speakers which are great
When I play WoW with a group of mates we skype and I use a USB plantronics Headset/Mic as the microphone round my neck - being USB it has its own sound card in line (in the cable)
Would I be better off buying an analogue Mic to plug into the z5500 control unit?
I have been told that it would reduce load on CPU and possibly sound better, as well as being easier with 1 driver for sound

Please help
