Well after looking at all the threads of the different mobos out I did finally decide to purchase this mobo

Here are my findings

Pros:

excellent packaging (like most higher end mobos)
overclock cpufsb up to 280mhz so far
overclock HT link and nb frequency up to 2500mhz
overclock cpu to 3.1ghz@1.29v (stock) 100mhz increase over sb600 @ same V (but I got a good cpu)
sb750 3.4ghz@1.45v / sb600 3.4ghz@1.55+v

cons so far: (may be user error until someone steps in to help)

cpu voltage only goes to 1.45v
have to lower cpu speed with higher nb/ht speeds(270+) again due to low cpu voltage
Havent seen any difference using ACC but Im still testing its been set at +2 for all overclocking so far.
heres some validations

Ill be posting more validations and begin testing in 3dm06, superpi (Useless @3.2ghz)

so if you see something that can be modified to give me better results please add in, also how to get higher volts in bios settings.

Thanks in advanced
