I have 2 of the older Gigabyte 7950s and at stock voltage doing OpenCL they run at 1200MHz.
Gigabyte had a number of the older cards that the fans wouldn't spin up and this was apparently a power problem.
The first rev 2 boards had 2 six pin connectors.
The next rev 2 boards had a 8 pin connector and a 6 pin connector (these pins don't stick out as far, their recessed)
Me and another guy have only been able to get the cards to o/c to 1140 stable doing OpenCL computing or hcc1 Help conquer cancer.
Also some motherboards have to have the PCI mode set to Legacy mode to get the card to work this turns off the plug and play capability for the other PCI slots.) This means you have to have a good video board to put in so you can set the mode to Legacy then take out a normal video card and put in the Gigabyte 7950.
This happened to me on Gigabytes own motherboard a Intel Socket 2011 X79-UP4 that is able to do 4-way CrossFireX.
