So far I have been using algo cryptonight by Claymore CryptoNote AMD GPU Miner v9.7 Beta for a long time and the result was like this:

GPU 1303/2150 -  total consumption 760W - hashrate 2818 h/s  https://imgur.com/meypJfR

I've also tried xmr-stack 1.4 and 2.0 (30 h / s better) have similar results:

GPU 1303/2150 - total consumption 645W - hashrate 2732 h/s  https://imgur.com/0FM5EL1

Bios card is original without modifications and config files are basics.
Does anyone have better results or are they a regular result ?
I have MSI 4xRX480 8gb, win7 64bit and driver 17.2.1.
