i haven't used the siberia v2 before so I can't comment on the mic. but if its anything like the steelseries 5vh2 mic, then i'll say its totally not optimal
the problem with these mics, especially when casting, is that there's only one small sound hole, so you're more prone to get the voice pops when pronouncing your B and P sounds.
the 5vh2 mic imho is the same quality as those 3-5dollar PC mics that are small and flimsy and come free with your PCs and have this really poor quality connector to the PC. so i'll definitely recommend against it.
so the difference in clarity of someone's voice when recorded on different quality mics is HUGE. my 5vh2 mic sounds staticky and lacks bass.
the at2020 that i'm using is bordering on a professional condenser, so unless you're gonna use it hardcore, i'll tell you don't bother.
as for mic/headset reviews, check youtube out and listen to the tech reviews they post up there, they usually include a voice clip with the headset's mic recording in it with some of these vids, might help.
the final decision however, comes down to what you wanna use it for, if you wanna produce VODs for high quality youtube broadcasts, i suggest you get a standalone mic, or a pretty good headset mic.
