if your budget was a little flexible you could go with some actual headphones like the hd518 or ad500x which would be better off than gaming headsets by far. both are open designs with large soundstages for good positional audio. open designs leak sound in and out however are better for gaming than closed designs. if you wanted virtual surround you can either use the free razer surround software, onboard virtual software if your motherboard has it or eventually get a soundcard which has it. as for a mic, you can pick whatever suits your budget and needs.
hd518- fairly neutral sound with decent soundstage and just a splash of bass.
ad500x-huge soundstage and great positional audio. more treble/mids focused without any real low end bass output.
the zalman clip on is a cheap mic though its not stellar. the moovmic boom is a little better but still not high end. other choices are clip on lavalier mics. the sony ECMCS3 perhaps. not sure how much you care about your voice quality compared with your sound quality on the headphones.
if you absolutely needed a "headset" (all in one type solution) then for $80 your best bet is the hyper x cloud. or if you stretched your budget the pc320 wouldnt be terrible. from what i've heard the usb soundcard issue was fixed on the hxc2. i've heard siberia headsets are fairly fragile and break easily.
