Goldring DR 150 or the Superlux HD 681 will do you well.
The superlux is an AKG rip off, although they out perform real AKGs at 1/4 of the price.
Again the Goldrings match/out perform more expensive headphones.
It would be a safe bet to assume either will outperform any gaming headset.
5.1/7.1 is pretty pointless compared to binaural sound (when talking about headphones anyway), its far more realistic and only requires two (headphone) speakers.
