the result is quite poor might bcoz of my p35 board that does not has dual pci-e x16 lanes and also pure pci-e 2.0.. and also bcoz of immature driver..

we've tested by oc the 3870x2 to 875 / 950 (from 825/900) and the increase is only 22 marks..

well i dun think the gigabyte card is bad oc card, coz so far i've seen most of 3870 has equal oc's ability..

maybe bcoz gigabyte is a latecomer?
