Priced at $149.99, the PCI Express Sound Blaster X-Fi Titanium Fatal1ty Professional Series features Dolby Digital encoding for single cable connection to home theatre systems.

The card also delivers accelerated audio for improved game performance, with EAX 5.0 effects and 3D positional audio.

"Audio plays a huge factor in professional gaming, where every competitive advantage can make the difference between winning and losing," said world champion gamer Johnathan 'Fatal1ty' Wendel.

"The Sound Blaster X-Fi Fatal1ty edition sound cards significantly enhance any professional gaming rig, enabling us to hear what we can't see and perform at our highest level."

Steve Erickson, vice president and general manager of audio and VLSI at Creative, added: "We've developed the PCI Express models of our Sound Blaster X-Fi gaming sound cards to meet specific requests from end users.

"We have re-architected our X-Fi processor so we can deliver even more performance and provide the best audio available on the PC today."
