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.)
