Teamspeak ? and associated hardware... Anyone planning on using this teamspeak program for D3? I have been aware of it, but i don't game with anything (until D3 comes) that would make it useful so I don't know much about it. Anyone care to give a quick tutorial for a noob on what it is/how it works. Further if you use it, what headset do you use/recommend? there are 100s and if i were to take the plunge, i dont have the $ to waste a subpar model. thanks for your time.
