^^^ I'm not sure what you guys are smoking but my rx480/580s went from 995 to 1015 xmr. Fix your -h values, 896 for 4gb cards, double that for 8gb.
One dude was spamming screen shots of his asus 480 doing over 2k xmr!!!!!!
His screenshots was with cryptonight-light algoritm , mining aeon which using only 1mb size , not 2mb as xmr , so its hashrate is doubled , so 2k aeon is about 1k xmr ,nothing special about his screenshots , ver 11 support cryptonight-light now.
edit: for 4gb cards -h 928 is also good , ( 896+32 ) , 960 goes to high then , no free ram to work.
