SvanirePerish :
Hello, I'm looking to upgrade my ASRock Z77 Extreme3 mobo, and have pretty much come down to these two options (but am open to others if they're $150 or less). Can anyone tell me, objectively, which is the better board feature wise? I know the Killer has more/better reviews, but It's hard for me to really tell which is the better featured board as someone who clearly hasn't looked at mobos in a very long time. Also, it's unclear, but how many fans can these two mobos support other than the CPU fan? Thank you.

1x DVI-D on-board video output ports

24-pin ATX and an
8-pin ATX12V power cable

Which motherboard is "better", objectively, depends on your personal needs and wants. You can use the above differences as to which ports/connectivity you require for your build and which features suits your tastes in determining what motherboard is best for you (as well as your budget).
