What Graphic Card should i buy?

You can get a really good Budget GPU like a 1050Ti (4GB variant) for around 100 to 150 bucks and it's totally worth it if you're on a tight budget I do personally own it and I absolutely love it but you have a little more cash to crank out you should be looking at a GTX 1060 (6GB variant) you can get these for around 300 or more.
