trying to pick cans is almost as bad as recommending a monitor; both are highly dependent on personal tastes. Consider these conditions as you look.
do you like phones that completely cover your ear, or just lay over the canal???
will you be listening to music on walkman's or stereo???? some cans need more power then walkman units can give
best recommendation is get to a good stereo store and actually listen to them; bring your own music so you know what it sounds like. As for performance, I love good music and would rather listen to my headphones, then most stereo systems. When gaming i can hear more sound and have better "relationship" to the sound, then with surround sound speakers. More then one friend has been spoiled after i've let them borrow my unit for the weekend.
this is a great place to browse and check out the different types
HeadRoom, plus their staff is excellent. For my use i have the Beyerdynamics DT-250-80's and though i have a good sound card with a dedicated headphone jack, i use a headphone amp to help boost the signal and clean up the sound. My kids are all addicted to headphones and the only drawback to the full over-the-ear style, is that they can get warm when the weather is hot (sweaty). But i wouldn't trade 'em for anything.
good luck
