    Out of curiosity, why do you run it with the nano since that's almost certainly resulting in worse performance than your 1070 Max Q?

    To be honest, its really just the convenience of a one cable docking solution for a dual monitor setup. I'm not a gamer, bought the gaming box enclosure used and got the r9 nano gpu from a friend. Since the aero 15x can't support multiple displays out of its tb3 port, I patch it into the egpu which can. Both the egpu setup and the native 1070MQ run adobe premiere and solidworks fine for my needs

    Is there any way to use de external GPU for something and the 1070 for other task?

    I'm not talking about SLI, just use it both for different task.

    Thanks

    I've done this in the past. sort of with different tasks/programs, but more so two different graphics cards for two different monitors from the same laptop. I think it only worked because the dgpu was an nvidia quadro and the egpu was a radeon fire pro something.
    It might also work if you have two gpu's from the same nvidia line - like both geforce or both quadro. I know for sure that you can't mix and match a geforce and a quadro since you can't install both the geforce and the quadro drivers on the same instance of windows.
    I think nvidia optimus can be configured to switch between dgpu and egpu(Rather than igpu and dgpu as its intended to do), but it might require some finnagling.

    Check out https://egpu.io theres a wealth of info there.

    I think is depend on the program. Some programs lets you choose which gpu you will be working on while some, mostly games, will not. Do you know what software you are using?

    Hi all.

    Today i Got the e-gpu and I did a few test with it.

    1 - It's not easy to install all needed drivers
    2 - It's not easy to understand the 2 drivers method
    3 - it's false that the d-gpu is faster

    I explain myself, first of all you have to unistall the lastest thunderbolt 3 drivers and install the one with version 16.2. If you don't do this, the updates for, in my case, gigabyte gaming box, won't install. So, first, unistall thunderbolt 3 software and install that version.

    The problems come when you connect the thunderbolt 3 to PC, if you get unlucky you will see a blue screen of windows, the big problem is that the driver for nvidia you installed for 1070 Maxq is not the same of the e-gpu will use, in other words, you need 2 drivers installed on your system, one for 1070 maxq and another one for e-gpu.

    If you install 2 different nvidia drivers for every card... blue screen.

    Shutdown pc, plug the tb3 and start windows, update driver, restart...

    Once you get 2 same drivers for dgpu and egpu, NOW you can rest, 1070 will be "inactive" and 1080 will be active by default.

    Good things about egpu:

    1 - If you use external screen, you can use e-gpu and d-gpu at the same time, one in monitor and the other one in laptop, this is ****ing usefull if you, for example, want to play in one screen (using e-gpu) and streaming in the other one (using d-gpu).

    2 - the performance of the e-gpu is not SO BAD, I checked a lot of videos on youtube about this, and the real results are not so bad, in my example, I've only lost 14% comparing with 1080 desktop, that is not the 25% or event 40% I saw on youtube.

    3 - My test on laptop screen vs external screen are nearly the same, youtube say another 15% but that is not true, in my case, 87 fps on external and 80 internal (less than 10%).

    All my test have been in 1920*1080, tomorrow will test 4k, and I think the difference between 1080 desktop will be even less than that 14%.

    Sorry for my english and will report if I do more tests

    There are many more laptops that only have 2-lane TB3. You have to do a ton of research to make sure you get 4-lane. Sometimes I've even seen people claim 4 and it ends up being 2.

    4 is definitely more common, but 2 is not as rare as you say.

    Can you check how OC scales on eGPU compared to desktop GPU?

    I'm very interested to see if overclocking actually changes the performance.
