As I thought the best route to go down is the external gpu BUT it needs to be connected to a thunderbolt 3 connection SEE BELOW
Thunderbolt™ technology is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices through a single, compact port.

So any high end model that has a thunderbolt3 controller.
What this will do is allow you to connect a RAZOR CORE that houses SLI computer type video cards and up to 128 devices in daisy chain also up to 2 x 4k @ 60hz monitors. Transfer speeds can reach up to 40Gbps.
if you have the money to spend the Titan GT80 series is excellent however i think if you check the specs the top model only has the Thunderbolt controller. Other models just have the 'Type-C 3.1 USB port' and not the thunderbolt 3 controller combo.
There is also backwards compatible thunderbolt2 Docks around for sale but you miss the benefits of the faster speeds.
The newer Thunderbolt3 docks are still in trials to achieve there USB-IF certifications so that these docks are compatible in all scenarios.
This is the one I am looking at. I pre-ordered it but it was explained to me that the company hadn't finished testing and certification yet. At the end of April several of these docks and devices will be available.
This Dock and its capabilities will change the way you use a laptop/notebook

Here is a Dell Thunderbolt3 controller.

Lots and lots of companies are getting involved with this technology but the development of Docks and devices is very slow.

And this one is been debated about on this forum.People are asking whether the Razor CORE works with a MSI notebook. The Thunderbolt3 technology runs as an industry standard, so Yes the Razor CORE by all rights should work.
