What great news! I've been running my Audigy2ZS happily on modified Creative drivers but could not resist giving this a try because of the Windows 7 x64 support. The sound quality is excellent and I have 8GB RAM on this system. No need to raise sound buffers yet with basic applications and stereo output but I'm keeping an eye on it. I changed the default sound output in Windows to Master Mixer and put the front/back swap back to standard as this card doesn't need it. I'm especially enjoying the 10 Band EQ again and next up is customising the DSP routing a little, only because it's possible. And the driver installation was so smooth. Nothing like the long Creative installations.
