Well is the 2.1 surround system enough for you or do you feel like you need more?
I would go for the headset if I really needed the mic and/or 5.1 surround sound.
thanks for the answer. It's enough for me. but I'm planning to build a new high end gaming system. I can go for a 7.1 or 5.1 surround headset or headphone. I just need to know is it worth upgrading to 5.1 or 7.1 or stay with my 2.1 surround speaker system???
