I'm using Tiamat 7.1 and its great. And i'm also a gamers, FPS mostly(CS:GO, COD, etc.).
From my experience the 7.1 at this headset is supeeeerrrbbb for FPS. Top front side back distance footstep from the enemy just cameout clearly. You can adjust individualy to get the exact volume you want to be for measuring distance the enemy, it's help alot for playing FPS. And the mic is just good enough for in game communication. The sub is enough for music or movies. What else...mmm its not heavy at all, earcups comfortly fit at my ear. By the way i'm just using on board sound card on my Gigabyte Z97X-OC Mobo. And in my personal opinion Tiamat 7.1 is worth the buck. And i will recomend you this headset
For references, before Tiamat, i have several headset, i'm using Alienware Tactx,its good to fullfill your need, but not 7.1 , then i have steelseries siberia v2, its also great headset, clear sound, good for FPS/music/movies except durability, i break 3 of this siberia in a year, maybe because too loud playing music, left speaker broke, 2nd because i drop it from my desk, It become noisy, it sound like im in underwater. I sell the 3rd one before i could break it LOL. Or maybe i just have no luck for siberia.
So thats just my personal opinion. Maybe it can help you to make the decision..sorry for my bad english, not my native language hhehe.
