The Audigy FX really isn't worth the money. It has a Realtek ALC898 chip which is basically what you get with on-board audio. The only thing your getting is the headphone amp and the software.
My favourite budget sound card is the Sound Blaster Audigy Rx. It's basically an old Audigy 4 pro on PCI express with an added headphone amp. It's a bit of a blast from the past and even supports fully hardware driven EAX 4 for all those who play older games.
