the title says it all....(actually I don't know what to write here, so I write this to tell you all :p)

Hello, I'm a newbie in terms of Audio (I don't even know how to compare a fake Beats Studio and the ATH-M30) but I know the M30's are better than the Beats. Anyway, how do you pick a good sound card? I will use the sound card for gaming and listening music but most of the time are listening music.
