I can back up point 3. The Darla would freeze a perfectly stable machine on a very regular basis. It and the asus p2ls wouldn't play together (the card was moved to different slots too). Yet a p2b would be okay. Both mobo and card were replaced and the problems continued. The eventual solution was to replace the card with another manufacturers. The problems went away immediately.
