Nice! Thanks for the update. Interesting that the old "need a dummy plug" thing reared its head again. Wonder if I still have one somewhere? There is a real simple way to make them out of the correct resistors (3) and a VGA plug. If I remember right YoDude on here had a bunch of them he made up awhile back.

Yeah, heat is becoming more and more the limiting factor on credits per day. I don't know if there is any other option than going full size tower case or open air on a bench with a house fan pointed at it. Even Cheetah and Puma are running hot and they are big cases with lots of airflow - easily on par with the HAF 932 I had, and the Thor V2 case is definitely larger and with more room than that.
My top card is always way hotter than the bottom one. Have you tried putting the 6970 in the top slot (and backing off the clocks on it if necessary), and then put the better 7970 on the bottom? This would allow you to at least get full blast out of the more powerful 7970 while only having to sacrifice a little from the slower card - if at all.
Just some ideas, but I think we're all in about the same boat...
