5558 wireless network card upgrade recommendations

I have 5558 Inspiron Win 8.1 and an AC 3160 M.2/NGFF Wireless Network Card  . The laptop will be upgraded to Win 10 eventually.  I would like to get recommendations on a upgraded Wireless Network Card to take advantage of my upgraded router/ 1 Gig speed download speed. I am currently considering AC-7160 and AC-8265.
