    Short version: The TB3 controller is only connected via x2.3 (16Gbps) instead of x4.3 (32Gbps).

    Thought it would be interesting for people that consider getting an XPS 15 9550 for eGPU purposes.
    Having said that I still achieve 10900 points with an GTX 1060-6 on the Firestrike Graphic Subscore
    without overclock which is ~83% of the desktop performance.
