I have the Z170X-UD5 in my cart ready to buy...
The PRO4 looks nice, but I feel it's a bit too lightweight feature wise.
The UD5 has more RAM multipliers so I might be able to tweak the RAM a bit more precisely. Also has voltage test points and I figure, this might be the last motherboard I buy for quite some time so I don't mind spending extra money on it.
Oh also, the rebates for the ASRock boards? You have 10 days from the day you buy the board to send that info in. What if the board is DOA or you don't like it? Or Canada Post loses the board in the mail? then I'm out of luck becasue I need to send the original UPC from the retail box....
The UD5 seems to be well liked from what I've read here and there. The UD3 looks like a solid board too so the UD5 should be a bit better.
I was looking at that ASUS board but their RMA department has me thinking against them. Plus the UD5 was basically the same price.
