Hi, I am interested in adding an external GPU for either my Macbook Pro 13" early 2011 or Macbook early 2015. I saw the AKiTiO Thunder2 PCIe Box and have seen some youtube videos showing it doesn't work on newer 2015 macbook pro retina models. I would like to add a GeForce GTX 970 or higher GPU to this device. https://www.akitio.com/expansion/thunder2-pcie-box Have you got this to work on older or newer laptop and is it reliable? I would like to use it for rendering in Final Cut Pro X as well as maybe using it for 4k monitor. The Macbook 2015 does do 4k but only 30fps. Will USB - C work with the Akitio with a USBC to thunderbolt 2 adapter? Will thunderbolt 1 on macbook 2011 be too slow for the Akitio? Thanks.
