After two replacement video cards and logic boards, I'm thinking there is a problem with the heat removal in the Imac. I'm probably wrong...In any case, the diagnostics show the video card is fried, so I'm now looking for a replacement that is as fast as the Nvidia FX3600 and does produce less heat than the Nvidia factory replacement
I have found several boards which will match the Mac layout, but I assume the PC bios will need to be flashed.
With that said, Apple should have a list of video cards and there power usage vs their performance. I sure can't find it.
On another note, my investigations have found the Nvidia Model P398 used in HP's and IBM's and other lesser known laptops. They don't seem to have the problems plaguing the 2008 Imacs. Same video card and less heat.
