I currently have my rMBP connected to a beautiful 32inch 1080p Samsung display. It plays games via Bootcamp really well, but considering it has two thunderbolt ports capable of sending 20gb/s, I was wondering if I could actually plug in an external graphics card. I know the MacOS would totally not support this, but I'm sure Windows would we be able to detect and use the external GPU. This would be totally awesome, because you could have the portability of the rMBP and also have the power to play the most intensive games at home. Does anyone know anything about this idea?? Does it exists? Is it even capable?
