RVN Mining Profit? Confusion!

Hey guys! I’m kinda new to mining with some real equipment, had done it before with some little stuff like 1-2 cards. I got my hands on 6 x 8 RX 570 4GB cards for a kinda cheap 5k€. all set up and fine. Now I’m a little bit worried about the profit. I can’t really calculate an accurate win / profit because every page is likely to tell me something different. Is there a trustworthy page? I’m currently running 4 / 6 rigs and I’m drawing around 4,73 kw according to SMOS. the Hash rate is around 420-440 mhs. Is that a good value? I tried Hive and it confused me to the end. But the Electricity value was much less. Is there a difference? How should I calculate all this correctly? I would be thankful for a answer. 🙂
