Did find a burnt Sapphire X1950XTX card with that arctic cooling all copper heatsink on it, and a few drills and threads later it's mounted on the XFX HD4770:


I must say that cooler is a piece of art, weighs in at a whopping 500g or so...all copper. They simply don't make them heatsinks that good anymore.
When feeded with 1.25v I get 40C idle and 50C load. ...and not even close to the noise as the stock coolers generates...

Did a 3D06 run with CPU@ 3.5GHz, GPU@ 1GHz and GDDR5@ 1.2GHz:
