sound card recommendation for x64

Thanks again to everyone for the helpful comments. I decided to get a Xonar DS 7.1 PCI card - very affordable + there is a rebate available through Newegg at the moment. Looks like it supports x64 properly and should be a step up from my Audigy 2.

Update: The Xonar card is great. 64 bit drivers work fine and the sound quality is >>> Would definitely recommend it if you're looking for a budget card.
