My Sapphire Radeon HD 7850 came in today!
Pretty good card, runs at 49 degrees on load with a modest overclock of 925Mhz on the core clock and 1250Mhz on the memory clock with the fan speed at 60%. Idling at 38 degrees with two monitors plugged in. The PCB is insanely smaller then my 6870 too, and only uses a single 6 pin power connector, whereas the 6870 used two. My 6870 was running at 51 degrees idle with dual monitors and around 56 on load with a game on a single screen.
Here is a visual comparison taken with my phone.
When I get a second, I will post case photos. Suffice to say I am pretty happy with this card, it performs well and is a nice step up from the 6870 in Borderlands 2, the slight frame rate issues I experienced are now gone.
