Built a new system...but.

Agreed but you have to buy the right M2, check their specs before buying and make sure your mobo is using its features.
Buy SS 950 pro, 941 or 951 , Kingston predator...
The M2 evo or others have the same specs as SATA SSD
For me, I think M2 is still not mature and still buggy in some situations. My Gigabyte X99 Force has an M2 slot and I thought about buying one but after much thinking, I will wait abit more.

I've been using SS 950 Pro since release on ~9 systems now and 0 problems except that it's way too fast

Are you using a cloned Windows install or a fresh install? I try to avoid MSI boards unless you're looking for a themed board. Either Gigabyte or Asus and for sure, since you're rocking a K chip, go Z170.

Read the manual and make sure you're using a Sata 6GB port. Also check into getting a board with a m.2 slot and getting a m.2 ssd.. this will BLOW away any sata ssd.

Kam it will be a fresh install.
M2 is too early for me to consider, the prices are decent but rather wait for more stability and price going down further.

Earlier in the day I told @Hunter that I was going to order the MSI M5 card, but after weighing all the options and I wanted something solid backed by great customer service & good bios update history I decided to try another Asus board and got the one above.
$200 jesus, pricey, but lets hope its a good investment.
Going to get it sometimes on Tuesday or Wednesday. After that I will return this POS mobo to amazon lol.
