MacBook external graphics card 2.0 (AKiTiO)?

Question

Video cards

Hello! I continued to dig information regarding the improvement of the video performance of the MacBook and came across another solution, this is AKiTiO Thunder2 PCIe Thunderbolt 2, in connection with this questions:
1. Which monitors can display the picture (external or main / external and main separately / external + main at the same time)?
2. Under what OC can I run this device (Windows or OSX / both)?
3. What kind of submarines are there?
4. !!! - Are there any analogues that are also connected via Thunderbolt?
Thank you!

Answer 1

my IMHO, although the connection of an external video card is possible (even on the mentioned AKiTiO), but this is nonsense. both functional and value for money.
don't torture yourself, people, or macbook: you need performance - assemble a powerful hackintosh.
