The Sound Blaster X-Fi XtremeGamer sound card delivers faster audio performance and intense, realistic sound in all your games. Headphone surround sound is better too - so good, you"ll swear you"re listening to multichannel speakers - and your games will sound richer as you hear all of the crisp, clear highs and bone-crushing lows you"ve been missing. It"s Sound Blaster on steroids.
