Supposedly MBP perform better than WMB but then I only can play Assasins Creed 2 on medium settings to play smoothly while WMB can play on all high settings with good performance.
Beside that, I do some crazy testing as well. I try to play the games on Parallels. Oh before that I forgot to say that both testing are done via Bootcamp. When you install Parallels, you can load the Bootcamp partition using Parallels which why I like Parallels so much.
I don’t have to say anything. On the lowest settings, the game look like below.
Assasins Creed 2 In Parallels
The skin are gone! 
Why is this? MBP damn it.
