What kind of sound cards can I get if I use this graphics card: 1GB DDR5 NVIDIA GeForce 460?

Trying to customize an order on HP's website. They wont let me add "Creative Sound Blaster X-Fi Xtreme Gamer" because it doesn't work with the graphics card, I can only use the Integrated sound. Are there any other sound cards out there that I can buy separately that would work with this graphics card?
