yes you are lucky to get a good chip I didn't get lucky with mine just because someone has to use a lot of volts to get to 4.5Ghz doesn't mean they are doing anything wrong.
As my 3570k needs 1.34 but hey I count myself lucky I have seen some take 1.42 to get to 4.5Ghz the old silicon lottery again
But what do I call stable well probably 2 weeks of general usage running 24/7, as you say prime is an indication only I normally do a 12 hour run on prime then I can be 95% sure its stable.
you are right that fact you can even boot into windows and do a 20 min Prime blend means nothing but it is an indication you are nearing a stable OC
