Sound Blaster X-Fi XtremeGamer PCI
A great sound card; I used it for several months. Might as well be brand-new for how it looks and how it performs. Save yourself some cash and buy this one instead of a new one!
Turbo charge your gaming experience with Xtreme Fidelity audio!
The Sound Blaster X-Fi 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!
Get the speed you need when every second counts
Win big with a powerful audio processing engine that boosts real game performance by up to 15% over motherboard audio and still gives you the fullest audio effects possible!
Hear your enemies before they find you
X-Fi CMSS-3D Headphone creates nine virtual speakers over stereo headphones for positional audio that's so accurate you can actually locate enemies by sound. Multichannel speakers are even better with audio cues that let you hear exactly where they are--even between speakers.
Enjoy truly cinematic movie sound
The Sound Blaster X-Fi sound card delivers THX certified surround sound for an unbeatable DVD movie watching experience.
Immerse yourself in a new dimension of sound
Shells and bullets whiz past your head. Massive explosions shake the room. Take reality to the next level with EAX ADVANCED HD sound effects in games.
Get lost in the incredible level of detail
Revitalize your compressed game sounds with X-Fi Crystalizer and hear crisp, sharp gunshots and deep, booming explosions for the most intense gaming experience ever.
Restore the details and vibrance to your games, music and movies
X-Fi Crystalizer repairs the damage that MP3 and WMA compression causes and intelligently enhances high and low frequencies for much cleaner music playback and more realistic movie sound.
Expand your existing stereo music and movies into surround sound
X-Fi CMSS-3D matches the sound to your headphones or multichannel speakers and positions specific audio elements--such as voice in the center and ambient sounds in surrounding channels, so your collection of music and movies sounds more alive.
Advanced audio and music creation features
A special dedicated audio creation mode supports near transparent conversion between any resolutions, digital-matched recording, low-latency ASIO support and much more.
