NOTE: I must say these AMD's run extremely hot! I had the iMac on again yesterday only in Target Disk mode. Regardless of how convenient, slick, and powerful a fully loaded iMac really is, it does make you reconsider the All-In-One philosophy and buying decision when a problem such as this arises. I know this tends to be "batch manufacturing" problems, but still would like to keep this iMac working for a long time, as I have with all of my other Macs over the years. Not that I had any previous problems with the AMD, but just to mitigate future problems. I kinda wish that my iMac could receive a completely new card other than AMD 6970M, such as the NVIDIA GeForce GTX 680MX 2GB GDDR5 used in the new iMacs.

I have an appointment for next week to replace the graphic card AGAIN, since it was replaced under AppleCare just 6 weeks ago for the same problem. I have exactly this iMac 27" sitting next to me with this very problem.
