I can't find a Mobo (LGA1151) that supports SLI



I see one, but it's an AM3+ socket.
Will AMD CPU's keep up with Intel's?
 


Far from it. Stay away from AMD these days. If your budget is fixed, get what Mr Kagouris suggested. If you can up it, get what i linked.

 


WildCard999 linked a Asrock z170 Extreme, isn't that a good one?
