Difference between these 2

[rook]

Looking to upgrade but can't decide on which to get. Had been looking at GIGABYTE GA-Z68XP-UD3P which is on sale for 140. But then I noticed a GIGABYTE GA-Z68XP-UD3 for 110. Besides the one having a mSATA port (which I won't use) whats the difference?

The big advantage to the GA-Z68XP-UD3P is the 12 Phases to the CPU, so if you're pairing it up to a SB (K) CPU it would be my clear choice between the two listed. More Phase ~ Lower vCore (Lower Temps, Longer life CPU, Stability of OC, Higher CPU OC).
