Before everything you need to know two things:
- Mining cryptocurrency on any graphic card supported by GamerHash is profitable
- Earning on Graphic Card with our App you use less electricity then playing a Video Game
When you are earning with GamerHash by GPU (Graphic Card) mining your CPU (Processor) is basically not used. Besides GPU your PC is using around 20-30W. Grafic Cards with full usage are taking on average from 100W (for example GTX 1050) to 250W (some solid GTX 1080Ti).
It depends on card generation (rule is that older card is more energy it will use) and model.
Higher model is series is more powerful and more energy consuming.
So coming back to question how much will you pay for it?
To count that you need to know how much energy is PC consuming (in Watts) while using GamerHash App. You can check that by using device called WattMeter.
