I second this is a great card running quiet even at full fan speed.

. noise level comparable to 5870 reference card fan running at 50%
Bought 5 of these recently, 2 could be shader-unlocked. It also has 2 dvi + 6 dhcp output for eyefinity which I don't use.
The only one I'm running atm(shader-unlocked) also overclocks well. reaches 1GHz at 1.2V vCore. But I'm running it 960MHz at 1.15V.
One quick question for the op how can you share how you reached 150MHz memory? Whenever I edit my memory clock in rbe and flash it back I got bsod at windows start. I asked other members they said the bios is signed you could not edit it. So far I'm reaching 600MHz with afterburner and asus smartdoctor in combination.
