One thing I've learned from past experience:
Never set your expectaions high, because if you can't reach it, you'll just be disappointed.
Nothing is guaranteed in the world of overclocking. There really are "golden chips" out there that will do X clocks on X low Vcore. Chances of finding one?
Slim.
Overclock your chip as high and as safely as you can and enjoy it. Max temps we want to see are 72C Socket, 62C package.
