Hi guys, Need some advice. I'm a complete noob in this area so if I'm asking the ridiculous please be kind! I've got a late-2011 13" MBPro with the 2.4GHz i5 processor and 8GB RAM running osx el capitan. It has an intel HD Graphics 3000 512MB Graphics card. Although I didn't buy it with gaming in mind, there are one or two games that I enjoy playing on it occasionally. One of them is a sim, for which the latest version asks for a graphics card with 1GB VRam with DirectX 11 Support. I read somewhere recently that the Pre-2013 Intel MB Pros are the only ones on which the graphics card can be upgraded. So my question is: Is it possible to replace my current graphics card with one that fulfils that requirement, and if so, can I do it myself and how much is this likely to cost? Any help and guidance will be hugely appreciated!
