430 Mhash/s
Temps: 75 C, fan speed: 80%, core voltage: 1.275 mV
1,000Mhz, unlocked shaders, underclocked RAM.
How does one know if it's a 'reference card' or not?

zamarok, could you please post the exact model and manufacturer of your card? I am highly interested.
Sure. Here's the exact line from my NewEgg email invoice:
14-102-914 VGA SAPPHIRE|100312SR HD6950 2GB R
And I bought it February 12th. I bought it for gaming, and only discovered bitcoin mining in the last few days. Glad I bought this model!
I'm at work, and it's at home mining 430 MHash/s for me. I only have the stock heatsink/fan, but I keep a regular table fan angled at it.. temps staying steady at 73C @ 1270 mV core voltage. I will keep tweaking it to see if I can get more Mhash/s without heating it up too much.Using the latest poclbm with GUIminer, CCC 11.5, -v 2 -w 128, 1,000 Mhz core clock and 400 Mhz VRM clock, and most importantly +20% OverDrive from CCC. When I first turned up OverDrive, my MHash/s went from about 335 to 390. Oh, and of course I patched my BIOS to unlock the extra shaders. Overclocking the core and underclocking the memory took me the rest of the way to 430.
