VIA chipsets are teh devil.
Never again.
I had to deal with all sorts of random unexplainable weirdness when i had my Asus K8V SE Deluxe.
Get yourself a nForce 3 mobo if you want to go AGP.
MSI Neo2 is certainly finickly, but great for OCing.
Epox has a good nForce 3 mobo as well.
And to all those saying don't get AGP, keep it to yourself.
It's well known that PCI-e is the way to go, but for those of us who have AGP video cards, selling the cards at a loss isn't always the best thing to do. Also, the nForce 3 platform is nice & mature, so any problems have already been identified for us beforehand
