    I'll bet you will do just fine. With my 1070, I think a large part of the instability I was seeing was related to pushing the power limits of the MB, which eventually led to some VRMs failing. The 1070 was running ~120W whereas the stock GPUs (K3100/K4100/K5100) were limited to about 100W, IIRC. A P3000 is much more conservative.

    In retrospect, I wish I would have tried underclocking/power limiting the GPU more.

    Ok so for information the P4000 is about 50% faster than the P3000 by looking at the graphics firestrike score.
    @lewis marx can you overclock or underclock or maybe tune the voltage ? decrease the core frequency of like 100MHz and compare the GPU clock before and after with GPU-Z sensor tab in GPU load
    Can you also show the tab in GPU-Z -> Advanced -> Nvidia Bios ?
    Thanks you

    Unfortunately all three overclocking options in afterburner bounce to 0 after changing. If you know of a way to change that I am open to suggestions but for know it is what it is. It's been very stable. More so than I expected after all the horror stories. It would be awesome if I could get even a little overclock top make it run closer to the mobile 1060 it's supposedly based on. Overall I would definitely recommend if you have the lvds motherboard and 1080p or 900p screens.

    Sadly it's the same for the Quadro P4000, no overclocking possible. The upgrade should work on both LVDS and eDP model, with the exception that the LVDS model need to keep enabled optimus.

    For comparison, from the Fire Strike score.
    P5000 is about 60% faster (I scored around 11,250) and M5000M is even about 15% faster (I score around 8,000).

    you are only comparing overall score which is a result of CPU and GPU, graphics score is a lot more meaningfull when we are comparing only gpu performance, for example you can have a GTX970 along with a poor 4c/8t cpu performing the same overall firestrike score as a GTX670 and an 8c/16t cpu
    http://forum.notebookreview.com/attachments/p4000-png.175350/
    In summary of performance (I compared FPS result of your P5000 firestrike run):
    P5000=1.28*P4000=1.9*P3000
    0.8*P5000=P4000=1.5*P3000
    0.52*P5000=0.67*P4000=P3000

    @lewis marx , can you show the tab in GPU-Z -> Advanced -> Nvidia Bios ?
