4+1 vs. 8+2(8+1) Phase Power Design

[xdan]

would say that is a 4+1 phase pwm.
The 6th "phase" is for the 790GX chipset.

+1 for what ?,if the six is for chipset? memory has it's PWM.

Nowadays a good motherboard has 3 or 4 mosfets (4 on ASUS motherboards ex: M3N78PRO motherboard).

That has no Amd 790GX/FX/XT chipset and neither SB 750 or 710.
This Asrock is the cheap 790GX(SIDE PORT MEMORY)+SB 750(ACC) i've found.
For what i want the cheaper Asus mb is 30$ fo for 4 mosfets it doesn't worth. And Biostar MB i can't buy because i can't find near bye.
