actually.... quite a few audiophiles prefer using the hd598 for gaming.
while its not "surround sound" (either multiple drivers or virtual) it does have a wide soundstage (since its an open design) which means that it sounds a bit more 3d than closed cans will.
sennheisers in general are not known for really powerfull bass. they have enough for gaming and listening but might not satisfy people who crave really powerful bass.
see for yourself what some audiophiles are saying about using them for gaming

some other headphones with a wide soundstage but not super bass are the audiotechnica ad700 and ad900 which are also well respected for the soundstage.

if you want headphones which have more of a low end...
audiotechnica ath-m50s
these can be had for fairly cheap and sound great. they have great sound and decent bass output. however, they are closed cans and are not known for a good soundstage. while i've used them for gaming from time to time you might want something of an open design. as you may have guessed, yes i personally own this pair of headphones and have for years.
beyerdynamic dt770 pro
a competitor to the m50s. it comes in 3 versions (32/80/250ohm). generally good sound. the 250 is the best but requires an amp. since its a closed design it might not be well suited for gaming however it does have a decent soundstage considering that its of closed design.
beyerdynamic dt880 pro
this is a semi open design so has a wider soundstage (although not as good as the hd598 which is well known for a great soundstage). they will hit harder though and are well respected for their sound quality. this is not a cheap option though and you might need an amp.
akg k701
while not great bass its sufficient and its an open back design which means its going to have a decent soundstage (but nothing like the hd598 or ad700/900). overall it gets high marks for sound.
you can hear the difference between the headphones here. keep in mind that this is just showing the differences.. and since its played over your speakers is not a 100% accurate representation.
