I have a asus g51 laptop. It is not under any warranty because it is 3 years old. Its sound card has stopped working. So I am thinking that I should buy a new sound. One of my friend told me that sound blaster x fi is the best sound card but as you all know asus company’s product do not support every sound card that’s why he is not sure whether it is compatible with asus or not. If it is compatible then Tell me where can I buy sound blaster x-fi sound card at a cheapest rate but not from any dealer in New York? I do not want any website name.
