The audigy is the newest breed of soundblaster cards (although Audigy 2 is out now) and features full advanced HD and EAX hardware accelleration.
The reason I bought the card was because I was tired of having to lower my multimedia properties to the lowest setting in windows in order to get a decent 40fps on GP4.
Since the card is a sound hardware accelerator, it takes the load of the processor and gives me superb sound with great graphics.
