new to linux and a bit confuse , can someone please sum things up for me ?

hello, i came here to linux for compatibility reasons for my new job but sadly only 200 out 900 steam games that i own do work on linux but i've heard then about wine and i'm still confused about it a bit , can someone teach me how to install fallout new vegas from steam through wine ? thank you!

btw does it require some high specs ?

my CPU : core 2 duo GPU : nvidia 210 ram : 2gb
