Hello people of all cryptocurrencies!

I can order some cards and I got list. Can you tell me what cards are best for mining in next 12 months. They are all AMD 570 or 580 chips, with 4 or 8 GB of memory. For now I'm mining ETH and I know memory is not that important, but maybe for future it is better to put little more money for some other coin.

Thanks in advance for your good advises! And here is the list:
