GPU Farm Suggestions

Does anyone have suggestions on what to do with my 8 gpu rig?

I have 8 cards all of them are AMD RX 580 4gb cards from sapphire. Nicehash now only estimates a $10 earning per card per month making that less than $80 per month (after energy costs)

Should i sell these cards or is there another coin I could mine that is currently profitable or looks to be promising?
