I want to purchase a 2013 iMac and use it for work and for gaming. Because the iMac has not a real good gaming card I looked for another solution. One of them is installing an external GPU (with thunderbolt) and use it with Bootcamp under Windows. One of the manufactures of these solutions is Vidock. Is it possible to hook up an external GP from Vidock (like they have done on :http://www.journaldulapin.com/2013/08/24/a-thunderbolt-gpu-on-a-mac-how-to/) and have a much better gaming experience?
