    SG mode is just not good really, I finally got the problem fixed and now the VR tests show my CPU is more than enough to run VR.
    Sadly even my 980M is still listed as some kind of bottle neck and might cause issues with VR, maybe two of them in SLI will solve the problem I'm not sure.

    Are you asking about using a 1080 externally or internally ?
    Internally the 1060 is the best you can have but requires modding the heatsink.
    Externally I'm not sure as I am guessing you would still need to install drivers which I don't think even exist.

    Fastest M18x upgrades possible for GPU:

    GTX 1070 (modify heatsink, SG mode only)
    Quadro P5000 (no modifications, SG mode only)
    980M SLI (no modifications, works exactly same as original cards)
    GTX 1060 (modify heatsink, SG mode only)

    So it is definitive? no 1080 (internal) for Alienware M18x R2? :(
    What you advise, 1070 or SLI 980m? (I want less problem as possible)

    980M SLI is the way to go for less headaches.

    980m SLI will be best for less problems. You will need to grind your heatsink and run strictly in SG mode if you want 1070. Also the 1070 cards seem un-reliable, which is why I went with 1060.

    No SLI support, but you may be able to utilize it in programs that can take advantage of multiple GPUs (not SLI) such as Hashcat.

    1160 might work next year if it fits and might be 1080 level, so who knows.

    I used the 7970m heatsinks for my 980m's. They don't need any modifications
