well i received my 2 yesterday along with 2 more gigabyte cards i scored a deal on and they are the weakest so far on the hashrates even with overclocking, the most i could get out of them is 1674Mh/s on skein, 12.4G/s on Blake, and 1120sols/s on zec so far.. they seem to be holding temps pretty well.. but do have a lot of room for overclock compared to my other cards.. just comparisons, my pair of gigabytes output 1775MH/s on skein, 13.2G/s on blake, and 1222sols/s on zec... im still messing with as i just got them up and running today and only spent an hour playign with settings im sure i can adjust more to get out of them, but that was hashrates on crude settings up tell freezing/locking up conditions..i will say this tho.. they seem to run about 4-5c colder than the gigabyte cards....
