Pascal Coin should be much more expensive. It is very hard to earn and it adds a lot of stress to the GPU and PSU as well. Since I am mining it already killed 4 GPUs and 2 PSUs of mine, using the Claymore miner in mode 'Ethereum + Pascal'.
I don't know if I am the only one experiencing these issues..

I will probably consider to only mine Ethereum without Pascal.
i'm mining the same way (eth+pasc) for 2 month.
no injuries among gpu's/psu's yet. ☺
5 gpu rig with 2 psu (1000 + 800 W).
maybe u should give more attention to power supply reliability and good cooling system for gpus.
