So, I have a set of Logitech G430's and an MSI Gaming 5 mobo. The headphones come with a 7.1 channel USB adaptor although I'm not sure whether my mobo's sound card is 5.1 or 7.1 channel. I have 3 options. Plug the headphones in through the USB adaptor into my mobo, scrap the adaptor and go straight through the back into my mobo or plug them in through the case port which is connected to the mobo through a HD audio cable (not sure if that will bottleneck the audio as opposed to having it straight into the back of the mobo). Another side question but if I were to use the USB adaptor, would 1.0/2.0 USB ports make a difference?
