I have decided on a 4770K and 16GB 2x8GB of 2800 memory. Would appreciate opinions between the ASRock Z87 Fatality Pro and the ASRock Z87 Extreme 6....haven't yet decided on a video card other than there will be one initially so that is of no consequence nor is the memory I've already chosen. I have already had two people that have no idea of what they are talking about say to use 1600, when I asked for opinions on 2800 sets of memory. Just wanted to be clear to all, I am currently looking for input between these two motherboards
