I'm soooooo confused , one post says E6850 can get to like 4GHz on default voltage while others need 1.55V for 3.6GHz.

My own E6600 has been running nicely at 3.4GHz with 1.4V in bios
So i'm trying to justify the leap to a new CPU, thing is...if i can't get 3.6-3.8GHz with a minor voltage bump to the E6850 is there any point?

Ergo...would it better to make the leap to a "G0" stepping Q6600 and enjoy the kudos of a Quad Core system

My ideal would be a Q6600 at 3.4GHz with say 1.4V...possible?
