I'm good with my XFX RX 480 8 GB cards. 3 GPU's mining at 80 Mh/s overall with 60 W power draw of each according to GPU-Z (of course I know that it's far from being accurate). Not much of overclocking done because I don't want my any of the GPU's to die or to lower the life duration.

You are doing okay and I think that is pretty nice, you also should not overclock it because it can get you into trouble and its also that its really lowers the life duration significantly.
These cards are by the way pretty powerful so that is nice.

What is to get into trouble for overclocking? If it doesn't work revert, it not like the overclocking police are going to come to your house, lol.

Also, it is not the overclocking that will lower a devices lifespan, it is the heat and/or too much voltage. If you can overclock a little, and in many cases with the BIOS mods, under-volt at the same time, you will not only lower the voltages going through your card, you will significantly lower the heat being generated thus prolonging the lifespan of your card.

As with all things moderation is the key, but for me I can pull a fresh RX 470 out of the box and get 22-23 MHash/s out of it with it reading about 70-80 Watts on GPUz and ~120 W at the wall. I can apply a simple BIOS mod, lower the default GPU clock, increase the memory clock, and reduce voltages a bit and up my hashrate to ~27-28 MHash/s while at the same time reducing my GPUz reading to around 50-60W and at the wall to under 100 W.

There is nothing wrong, illegal, or immoral about this. It is simply re-tuning the GPU for a different purpose (mining) than what it was tuned for at the factory (gaming). Considering these cards have the lowest common denominator for settings so that the absolute worst binned part will perform ok, in most cases there are significant improvements to be made over factory defaults.

Overclocking done right can give the most performance out of the cards. At the same time if one is not good at overclocking, it is best to leave it alone. I am totally new to overclocking GPUs safely. Do you have any good tutorials or links to good videos to start with? I am sure experience is the best teacher, but I don't want to burn any GPUs trying to overclocking it especially when I can take good advises from the experts in bct.

You are right. But the mining profitability is not so high now. So if you pay high electricity cost, it is better to downclock.
