im getting the Logitech g430 and it has a built in sound card for surround sound. but as i read reviews, they suggest that the usb sound card is not up to the mark and suggested to directly plug the 3.5mm connectors(it has kind of like a removable 3.5mm to usb sound card ). i checked if my mobo had support for 7.1 and it did. so now what should i use? would it make any difference? and also if i had a stereo headset, and i plugged into my mobo 3.5mm jacks, would i get surround sound or just stereo? does surround or stero depend on the device or just the sound card ?
