there seems to be a higher chance to have a good clocking card if it has a low vid, but the differences seem to be rather small, at least on air and from the numbers you guys posted so far...

thesis: lower vid = higher oc
the 3 480s with the highest voltages all clock notably below average
one of the worst reported 470 cards has the highest reported vid
the 2 470s with the lowest vid are notably better than the rest

counter thesis:
rank 4, 5 and 6 of the 480s clock almost the same as the 480s with the lowest vids, at least on air and water
the card with the lowest reported vid for a 480 does great on ln2 but is slightly below average on air
even among cards with the exact same vid there are fluctuations of 33-75mhz, while the worst to best clocks are only 125mhz apart

from these results there is definitely a trend id say, but its not linear scaling...
lower vid = higher chance to have a good clocker, but the most obvious results are that high vid = almost certainly a bad clocker

for 470s the trend seems to be stronger than for 480s from these numbers, which makes sense as there is more binning going on for 470s than 480s...
theres a much wider range of gpus with different specifications that can end up as a 470 than there are for a 480 candidate.

for 460s there is no clear trend from these few numbers...
the lowest vid clocks the worst and cowie tried two cards and found the higher vid card to clock slightly higher...
