Don't let those extra 2 channels got to waste, pick up a 7.1 speaker system, like Creative Labs GigaWorks S750.  Laptop Gamers has posted a review.

"This THX certified speaker system delivers an unbelievable gaming experience when combined with a

7.1 sound card such as the Sound Blaster Audigy 2 ZS. The S750 also comes with a wide range of

connectors including line-in, M-Port and headphone jack for connection to stereo devices and

portable audio players such as the Creative MuVo NX MP3 player. The system also includes a handy

wireless remote control that lets you adjust mute, power on/off, individual output levels and

treble/bass settings to your own preference."
