Have an 4850 OC'd 1GB... it was running at 700mhz but i started having issues with it overheating and turning my rig off... currently have it running at 500mhz

Was getting about 82M hash/sec @ 700 MHz
Am getting about 58M Hash/sec @ 500 MHz

Also in another machine have a 5750 and it is doing about 105M hash/sec

Edit: 4850 was a Manufacturer overclock (also came stock with a zalman branded cooler).

Finally with some help got gpu mining going on the 4850x2

getting aproxx 70,000 khash/s on each side of the dual gpu card, and can still play vlc 1.1.7 full screen wideo but it crashed overnight, which if it's a heat issue, that'll be something
as my card has the xspc full cover waterblock on it.  Special thanks goes to ] Keefe]who setup the poclbm miner on a fresh system with the latest CCC install including the most up to
date drivers and CCC and SDK on the FRESH install of win7sp1 with all the latest updates....

if you havea 4850 and want to share tips I'm on the twitter and the facebooker things

time to get a coffee,
