I used to mine a while back and have two 2GB sapphire r9 270x, now I'm back and scrypt is all ASIC.... X11 is ASIC.... ETH can't be mined with 2GB cards.... most of the new ALTS I see being created are now ICOs on ETH and not mineable currencies... is there a list of coins still mineable with GPU?
try to mine the clone of ethereum they use the same algo, you have some choice, like musicoin or ethereum classic, with classic i'm afraid you can not diff too high but with musiccoin you can use 2gb card
