R9 390 has better memory and a more refined manufacturing process that lets it overclock better than the 290x. I just bought the sapphire r9 390, it's amazing. I overclocked it and it beats a gtx 980 in firestrike/firestrike ultra/firestrike extreme.
thanks for your reply
but dont they have the same memory(hynix)
correct me if im wrong
IIRC there were 290's and 290x's with hynix, elphia, and samsung memory.
Not sure about the 390's and 390x's
