Just to add a "me too..."
GA-7VRXP rev 1.1 and F4 BIOS with an Athlon XP 2000+ running at 1.80GHz (144MHz bus) with very few problems.
I occasionally have a 3D game that locks up, but I think it's more related to my overclocked Radeon 8500 than the motherboard; Win XP reports a video driver error. I've never had a non-3D app lock up, except during extreme FSB overclocking.
Otherwise, the system seems rock stable, and I'm quite happy with my purchase.
I've been unable to raise my bus speed above 144MHz, but I suspect it's my processor (not unlocked) or RAM (generic PC2700) holding me back.
The on-board sound is just fine for me using decent Altec Lansing speakers, the on-board LAN is just great, and has more USB ports than you can shake a stick at.
