Alright so I'm looking into making a good sound setup for gaming. I want a HEADPHONE as I'll be purchasing an At2020 so I don't need a mic. I play games like CSGO, Arma 2/3, DayZ, Fallout, Skyrim, GTA V, Gmod, etc. I'm looking for a headset that is good for competitive games (like CSGO) (as I wanna be able to hear the enemies' every move) yet good on the immersion side (if I'm playing Fallout, Skyrim, or scary/story mode games). So I was thinking of getting either one really good headphone that's good for both or 2 pairs that fit each category (and I'll switch it out depending on which game i'm playing.
For Immersion I was looking at: http

For Competitive play I was looking at: http
/www.amazon.com/Technica-ATH-AD900X-Open-Back-Audiophile-Headphones/dp/B009S331VU/ref=sr_1_1?ie=UTF8&qid=1449703614&sr=8-1&keywords=ad900x
I couldn't find anything that's good for both competitive play and immersion without sacrificing anything.
If anyone has any experience with these or can recommend any others that fit the bill that'd be awesome.
I also have the motherboard: http

Will the Onboard audio be good with these? Or should I buy a soundcard?

Is it good?
Orrr not being a huge "audiophile" I legit just want a headphone where it can sound good and have like directional hearing yet be immersive.
Should I save $150 and just get

or is it worth it to invest in higher quality sound? Is an open headphone (like the ad900x) as good as virtual 7.1 audio? Kind of new to this.
