Hello everyone! I have been reading here for several hours now and I decided that I wanted to try to use my rMBP for gaming using a eGPU. (Ofcourse, in bootcamp) However because it isn't stable for everyone I first want to see if it works for me without paying allot of money. What is currently the cheapest way to connect a GPU to my rMBP? I don't care if the performance will be around 80% or so, also no case is needed. I can always buy something afterwards when it works. So far the cheapest and best thing I found is the AKiTio Thunderbolt 2 -> http://forum.techinferno.com/enclosures-adapters/7205-us%24189-akitio-thunder2-pcie-box-16gbps-tb2.html Anyone got a opinion about this?
