I am web developer, can i use my working pc to mine and work at same time? Guyz, i am a web developer, i have single pc but i am thinking to add a good GPU in it, my question is that if i add good GPU, will i be able to mine crypto currencies like BTC/ETH and work on my pc at same time? will it be OK ? Kindly share your opinions experts. Thank you
That would be possible but probably not profitable. 

If you use your GPU to mine BTC the costs for electricity are most likely higher than your gains from mining. 

I don't know if GPU mining is profitable for ETH. That also depends on where you live and what you have to pay for electricity of course.
