    Not really with Haswell, since the voltage regulation is done on the CPU itself. You don't have to worry about power delivery with z87/z97 nearly as much as before.

    The phases will affect overclock,more phases can let more stable when i overclock,like msi or asus use 12 phases to push the motherboard to overclock,it will let overclock success and more stable.

    Even though basic core voltage is controlled internally, the better and more stable the filtered voltage that goes through the primary CPU input voltage, the better it will be going through the internal VRM. If one wants to overclock to a decent amount lower phases like 4 are fine, but to eek out more and get the most OC for the lowest values, more phases tends to help from my experience. I have been able to tweak my board more easily than a similar but fewer VRM setup on an Asrock board.

    doesn't matter in the slightest with haswell unless you are pushing the chip really hard any one of those boards will be fine
