I have just purchased a brand new 15" Retina Macbook Pro, I bought the high end model with the graphics card so that I could do some gaming via bootcamp, I'm interested in downloading ARMA 3 through Steam but I wanted to know if it is worth the purchase as I have heard the game is quite taxing and wanted to know if my Mac can run it at decent (mid-high) settings at around 30FPS, its £40 after all and I was just wondering what I can expect if I do purchase it
