I have 2 270x which i bought in december under 60eu, i roied them in about to weeks back then. They are bit power hungry but as long as u have cheap electricity ( i have a flat fare) they will be making a profit, not much these days though. They dont have many good algos but here is my combined hashrates with what i mine, mind no bios mod.
criptonight v7 : 930h
equihash: 395h
neoscrypt: 1150h
ethereum: 21mh
i run them at 80% so the power draw is around 300w forr both.
