funcut :
I will buy 925 and OC to 3.2 GHz.
Btw. What MBO should i choose Asrock M3A770DE or 770 Extreme3?
It's a matter of taste. Extreme3 is a bit better but also a bit more expensive.
The biggest differencies are :
Extreme3 supprts up to 6 cores, M3A770DE only 4
Extreme3 supprts SATA600, M3A770DE only SATA300
Extreme3 supprts has Realtek ALC892 audio, M3A770DE only VIA VT1708S
However Extreme3 has only 1 PCIexpress 2.0 x 16 slot. M3A770DE has 2, running X16 and X4 mode respectively.
So it basically is a matter of which components you're going to use.
