Please do not buy the z2300. These are very cheap speakers, and while they may sound ok for games, their music quality is really lacking. Ive found 15$ speakers that actually sound better when running media player.
For quality I reccomend these: http://www.newegg.com/Product/Produc...82E16836116006
You lose a clunky sub but dont really notice the difference from the z2300's already lackluster sub (if you do turn it up, the overall sound becomes degraded).
Id get the Audigy 2ZS or the xtreme music if I really wanted to spend extra money.
