i was going to buy a new mainboard. betwenn Asus P8P67 or Msi P67A-C45 which is better and why ? If u help me it would be very grateful to me! Thx in advance.
It depends on your CPU choice, the ASUS P8P67 (REV 3.1) is 12 Phases and the MSI P67A-C45 (looks like 6) I realize the SFC are supposedly more efficient they're not doubly as I recall 20%~30%. Nonetheless, the transitions wouldn't be as smooth which would required to compensate between the drops/spikes between phases -- which translates into higher (bad) vCore.
Next the ASUS adds Marvell SATA3 ports has more USB ports. I also like the added PCIe for example RAID, PCIe SSD, etc card.
