Hello as I said I'm a bit newbie in terms of mining. I want to try out GPU mining if its possible and got some few questions and hope that someone can help.
1. First is, is still profitable to mine using just 1 card? My plan is to try one gtx 1080ti or 1070ti (just ignore the electricity consumption factor).
2. Will it be possible to plug it on my workstation and be able to do my daily tasks on my PC and be able to mine. (What I mean is just using my onboard graphics and letting the GPU to mine.)
Yes, you can do that but the profit will not be very big. Taking into account that your workstation will use electricity for your other components, I would recommend having as many GPUs as you can fit in your workstation and of course, what your power supply can sustain.
To get an idea on what you can make with certain GPUs you can check out this website:

Also, to see your overall workstation power consumption you can check out this website:
