Was about to get a Steel Series Siberia and wonder how was the mic and everything works. Since the Siberia v2 price is almost near to the Roccat Kave which i think would give a better performance, some told me with RM339 there are still better choice to get, so whats your opinion for a RM339 around headset. Also, can i use my motherboard EP43-UD3L onboard sound card to run the Roccat Kave, will it affect the 5.1 sound quality?

Please give your opinion towards this Kave or recommend me some below RM339 headset.

Thanks in advance.
