ASRock z77 pro 3 or pro 4-m?

just wondering which is the best MB for overclocking a 3750k to about ~4GHz.

my build is:
i5-3750k
Zotac GTX 650 Ti
Corsair Vengeance Black PC12800 8gb (2x4gb)
PSU Corsair VS550W

so here's the pros and cons of each MB in my perspective:

pro 3:
+ ATX form factor
- 4+1 power phase

pro 4-m:
+ 4+2 power phase
- mATX form factor (which in some reviews, i read that the PCIe 3.0 slot is too close to the HD audio port, so if i managed to install a VGA on it, i can't properly use the HD audio port, vice versa)

i dont care about SLI/Crossfire thing, since i wont use that any kind of feature.

tangled to a ~700$ budget, i wasted a big slice of my budget to the processor,VGA,and LCD (~450$), because this's gonna be a gaming rig. after adding PSU,casing,and RAM, leaving a ~130$ space for a choice of Z77 motherboard.

is the power phase gonna make a difference in performance and lifespan?

is there any other option available in the ~130$ range?


answer will be very appriaciated,
review of overclocking on both MB also can help :)

PS: sorry for my bad english :D
