investing in an gpu is for the players who has double purspose. investing on a gpu is for the gamers and at the sametime for the miners. investing on a gpu if your not a gamer whill just end up stocking your gpu for a mining purpose.
if youre not a gamer better invest on a specialized machine where it has to do with mining bitoin. somehow this machine helps you to earn and at the same time has a low rate of electricity bill.

@OP Go for RX 470 4GB version. Best value at the moment. As for what basesaw said, better buy GPUs, since when you are done with them there will be someone still wanting to buy them so you will at least make some of your money back in case you fail
