i have since changed the clock speed to 783/1566/1296.
i used riva tuner to OC and that doesn't show the 2:1 shader:core, and i used precision later to correct that.
its called look at my vantage gpu score, its almost 12k... and its validated.

1) turn off physx ffs (you can't upload scores to vantage with ppu enabled and its actually showing cpu+gpu score)
2) 1.5 V for q6600 = the cpu probably don't like you too much
i'm using stock cooling (@100% fan)
heres my pc profile

these are with physx off.
physix on = ~ P14.5k , H9k+
QFT
i'd go with xfx or evga cause their warranty covers mods on the gpu as long as you don't mess up and physically damage the card.
BFG, a gamer's brand, won't cover OCing... wtf?
gpu score = average
cpu score = artificially inflated by physX
turn off PPU in the options page on the bottom right
my q6600 (g0 crap overclocker) gets around 11k cpu
