I agree with Dave.
I keep telling Ninja_Boy to stop telling people that the chips are all good for like 3.6Ghz on Air. Nobody knows til we see more out.
You can bet on maybe 3.2Ghz on air with decent temps, but until there's a slew of CPus out, going off of the handfuls that have trickled down just isn't enough.
Now may someone get a relatively poor performing G0 that overclocks worst than the best B3? Sure. But we are talking about the big picture here. The G0 is a better overclocker.
