Frankly I don't build high end AMD systems any longer since my client demand no lockups and perfection. For some reason AMDs tend to be less stable and require more tinker time and hand holding then 2 years pass and well, the stories are out there. We will build what they want but hangs and BSODs on AMDs are legendary. Not that Intel is immune but we had far less troubles there.
