Yeah, and the nForce3 Pro 150 too? We want something to drool over!
Macro2, I did just do some testing of an Asus A7N8X-X here at home, including playing UT2003 Demo with 63 bots

It performed well, all things considered (CPU ain't so fast, just a 1700+).
Interestingly, the audio was quite good despite having just the MCP southbridge, and the audio driver is still nVidia, not third-party (I used nForce2 2.03 drivers). I used Hardware 3D Audio + EAX in UT2003 Demo, sounded good to me (and my usual gaming board is my A7N266-VM, with the full nVidia APU). Overall, it felt quick (and yes, I did have IE and Windows fully patched-up, so it's not just that it had a raw, unencumbered Windows installation).
A couple other random notes on the A7N8X-X: it has no gameport, nor a gameport-on-a-stick bracket; it has an S/PDIF header (hmm!); it has three fan headers despite what the manual says; and it has holes around the CPU socket for bolt-down coolers.
