Hello, I have a late 2013 Macbook Pro with Retina with the following specs. 2.3GHz Intel Core i7 16GB 1600MHz DDR3 512GB SSD Intel Iris Pro 1536MB Graphics It is setup to dual boot in to OS X Yosemite and also Windows 8. I have steam installed and play games such as Civilization and Command and Conquer but am considering trying some FPS games. Does anyone have any experience in playing FPS on their Macbook Pro? Can anyone tell me what kind of gaming PC the Macbook Pro would be comparible to? I am considering investing in a stand alone gaming PC but don't want to purchase one of similar spec to my Macbook as there would be little point. I will be using an external monitor, gaming mouse and mechanical keyboard for gaming. Any experience?
