how should i upgrade my GPU

[DefectedSOul]

I currently have a AMD R9 390 card in my pc and later down the road when i want games to run better should i get another 390 and put in my pc? or try to sell my card 390 and get a Fury card
or how should i do it?
i know its all around better to have 1 card over corssfiring 2 lesser cards but i already have a 390 now
(im not posting my whole PC build here because by the time i do upgrade the gpu im going to have a new mobo and new CPU (planning on upgrading those when zen launches and if its better ))

in games with crossfire profiles, the 390s would be easily better. in games without one high end gpu is usually enough anyway.
