Please recommend sound card with solid WinXP x64bit support

[chunkymonster]

As the subject states, looking for a quality sound card that has solid/proven WinXP Pro x64bit support.

Currently am using an M-Audio 7.1 Revolution on x64bit beta drivers with no production drivers expected anytime soon. Been playing GTA:San Adreas and the sound is causing the game to stutter and chop, also getting some sound anomolies with music and video too. Reading the reviews and sites, there aren't many sound cards (X-Fi, Auzentech, M-Audio, etc) with non-beta drivers available for x64, so reaching out to everyone asking for some input, experiences, and recommendations for a sound card with good x64 driver support.

Specs are as follows:
2 x Opteron 252's
Supermicro H8DCE (nForce Pro 2200 & 2050 chipset)
EVGA 7900GT KO
M-Audio 7.1 Revolution

Thanks!

wow, nice cpu's
the only way to go is the creative xfi's it's the best and any of the cards in the xfi line would do, i'd get the ones w/ a front i/o then u would be able to get more options for input and output.
they worked perfect for my windows x64, i dl the driver from the creative site but i'm sure its on the cd though.
