dude, u have a AMD mobo, and u're asking if u could fit intel CPU on it?
no offense, but have u ever seen someone build a thing that supports their competitor's product? (like a Razer Deathadder able to be synced into Logitech Gaming Software? or a Rival 100 controllable with CUE [Corsair Utility Engine]?)
no? well, figures...
Technical answer:
No, No, and No....
FX series uses AM3 socket (from AMD)
while i7 7700k uses LGA 1151 (from Intel)
7700k also uses DDR4 RAM which means if u're going to upgrade, u gonna have to say bye bye to your DDR3 RAM too (more expense)
if u're going to upgrade, u're gonna need a new mobo which supports the socket that ur CPU is going to use, new RAM according to your new system (most new gens uses DDR4) and an aftermarket cooler (if u're purchasing Intel's K version CPU)
