OK I am a little nervous...
System 2011 iMac i5-2500 16GB RAM, newly istalled 780M with BR3 vBIOS from nicky22, High Sierra.
Seemed to work great. Ran Unigine Heaven fine, results as expected. Same with Geekbench 5 Metal.
I then tried with Valley and left it. Came back and it had restarted with a kernel panic crash report (below).
I then tried Valley again. I stepped away just for a moment and heard it shut down. There was the grey screen "your computer restarted because of a problem" error with green vertical lines! Ahhhh! Panic. Shut it down. I guess it is overheating so would benefit from copper shims...but have I already nuked the card if I got the green lines?!?
Here's the panic report:
