I have been having nothing but problems with my xfx 260gtx black edition. I was getting random crashes and artifacting. After doing some research, it turns out that the factory overclock is unstable on many of these cards. I downclocked the card to the non black edition, and some of these problems went away. However, I now get random bsod's when watching youtube videos or playing certain games. The minidump is included with this post.
