I am selling a Creative Sound Blaster X-fi Xtreme audio PCI sound card. I originally bought two of these intending to make 2 car computers. But the second computer fell through so I never used this sound card.
The audio quality is 100x better then on board audio, it uses a PCI interface and has a X-fi chip that has the crystalizer that makes the audio sound amazingly clear. This card can output to 5.1, 6.1, and 7.1 channels.
Also included is the headphone to RCA cable from creative. this converts the headphone jacks on the card over to RCAs. There is a RCA for Front L&R, Rear L&R, Surround L&R, Center, and Sub.
If you have any questions feel free to ask!
