I am targeting 4.5~4.7 GHz Hopefully.

What he said.
If you're not aiming at something extreme like 5GHz+ then this question is rather easy to answer: watch your temps! With your setup, i bet you can't go any higher on vcore than 1.45v or something before you hit 90C under load. Put your GPUs on load at the same time and your temps will go up rather quickly. Just stay below 90C (real) core temp on any of the six cores.
On the other hand, to reach 4.5 on a 3970X you won't need that much vcore anyways. I have a cheapo 3930K and it needs a mere 1.285v on vcore for 4.5GHz...

I have another tip though: Maybe you wan't to give vcore offset a try. I really like this type of vcore adjustment and as long as you are not to extreme on the clock it will propably work. What this basically means is, that depending on load your CPU has different voltages based on the VID of chip. For my 3930K, i need an offset of +0.09v for 4.8GHz (LLC on 1 step above the middle setting, don't know what its called, medium? high?). This nets a vcore of 0.85~0.92v on idle (wich helps a lot with idle temps and power draw) and on full load with prime95 small FFT it goes up to 1.4~1.42v (measured with CPUz).
The difference in power draw measured at the wall is quite huge though. My system sits at around 240W idle, but running prime95 it goes up to like ~620W or something. So much for that 130W TDP rating.
I know there isn't only the CPU involved, RAM and VRM take there parts too, but honestly i wouldn't pay too much attention to that TDP rating anyways. 8)
