I bet it runs at 80c in good conditions, that fan style is not good. The cgminer pic looks like it just got turned on.

my guess is 1000-1200 I can get 600 when pushing my 7950 at 1150/500... |

WTF IS THE MH/S!?!?!
my guess is 1000-1200 I can get 600 when pushing my 7950 at 1150/500... That's a 7950. This is 2x 7970s, which gets 550MH/s per core at 925MHz, which is exactly what was expected. Switch to the alternative BIOS, which OCs to 1000MHz, and you should get almost 600MH/s. Pic from the Imgur in the first post: http://imgur.com/a/kFqHC#1 |

Dude has a 7990...and a PATA dvd rom? Can I donkey punch him for that? Or did he save all his upgrade money for the past 10 years for the 7990 and couldn't afford a new DVD-rom? What decent motherboard even comes with PATA anymore?

Huh? On my 5970s they showed up as GPU0 and GPU1, very similar to what that pic looks like. |

Yeah two cores will show up seperately for dual GPU cards. Seeing as how my 5970s get ~360 each at 810 core, coupled with architectural and clock improvements, this sounds very reasonable to expect (550 per core).

Running 2 7990 cards. These look like made of binned 7970, the ones with the lowest heat dissipation at given voltage / speed. They can be nicely overclocked in an open case to around 1100Mhz in a cool room ~70F. At 70 - 80F these are happy to run at 1GHz. The voltage of one core is adjustable but another core is locked (unfortunately). Speeds of both cores are adjustable. |

I went and bought 2 of those 7990. They are very nice hardware, easy to fit 4 GPUs in to somewhat normal box and just leave the sidepanel open for the heat to escape. And there are some benefits of 7990s in gaming too  |

I looked at 7990s over 7970s last night, it doesn't make sense to me.
ROUGHLY same power consumption, ROUGHLY same max OC, same hashing power at same clocks.
But 2x7970s £560 and 7990 costs £730+ if you can find it. Even factoring in reductions in 'specialist' motherboard requirements for the equivalent of 4 cards, and case requirements, it doesn't come close to paying for itself.
