Recently, my Turtle Beach X12 broke and I have been looking to buy a headset ever since than. My budget is 110 dollars, basically im looking for a headset that has good audio (preferably 7.1) and a mic (and again a good mic). I was thinking of a Razer Kraken 7.1 but I came here for more options I mainly play CSGO, so a good 7.1 will help me in it but occasionally I play BF3 and some BO2.
does your onboard soundcard have dolby headphone or virtual surround support? if so pick up the hd518 and a boom mic like the moovmic or modmic. if it doesnt, perhaps use the xonar dg soundcard with them. virtual surround support would give you 5.1/7.1 on any stereo headphone and headphones are going to be superior to gaming headsets in terms of audio quality.
if you want an all in one, perhaps the hyperxcloud or hyperxcloud2
