    Yeah, you can upgrade to 1070. @thegh0sts can give you the steps. And you can use the new 780w psu.

    me and @Coolane both use the MSI GTX 1070 which looks like this:

    firstly, if you have a Gsync display in your laptop the image will look corrupted (like a deinterlaced image that looks like it stuck between a frame change) - this is because the motherboard does not recognise the 1070 as a Gsync compatible card. you'll need to flash the GPU to fix the screen corruption (you'll have to work through it) but it does mean you'll lose Gsync. a minor trade off but meh in the long run. i still have a copy of the vbios you'll need to flash and i am ok with sharing it.

    we both use modded GTX 980 heatsinks to cool the 1070 because it has 2 banks of heatsink fins instead of the single heatsink fin of the 980M heatsink. below is the thread i made over at techinferno about the mod.

    https://www.techinferno.com/index.php?/forums/topic/11137-p870dm-g-980dt-heatsink-mod-for-msi-1070/

    finally, you don't need the 780W PSU since the GPU TDP is low that you won't even go over 330W. you'll be in a more advantageous position if you have the Prema BIOS.

    Yeah, 780W for a single step down from top card is total over kill.

    With the default vBIOS, a stable overclocking can bring you about 10% improvement on performance.
    Probably you can use the 780W power supply, but I think 330W is sufficient.
    If the system BIOS added the support for 1070 in the future, I guess G-Sync is possible. But so far there is no update BIOS for P870DM1 yet.

    330W will be sufficient even with high CPU & GPU overclock. Don't worry about it.
