So lately I was thinking about upgrading to an RX 590 or a GTX 1660 from my RX 570. (It's an ITX version with cut down Memory Clock, 1500 MHZ/6000 MHZ Effective.) But is it worth upgrading to an RX 590 or a GTX 1660? (Maybe Ti version If I can find a cheap one for like 250$.) Or should I wait a bit more and see the new GPUs? (I don't like the fact that I bought a cut down version for the same price of a normal one.)
