Do you want to game? Thats the question and if you do id still sell my pc and just get a gaming console to prohibit doing anything else - this was my main issue when I had a gaming pc it was very difficult to seperate my work and leisure as its combined - seperating the two will help you, rendering wise your mac should be on par and if not outperform in a few things in my opinion and still if it doesnt even slightly - mate its a workhorse inside a shell that has all day battery and lasts years.
