    Can I use an eGPU on my HP Envy-j100 Quad Edition?

    This process is very confusing and frustrating for me as I have no experience with this or graphics cards in general. :nah: Here are the specifications of my PC you may need to know. Tell me if you need anything else.

    10 GB RAM
    Intel Core i7-4700MQ CPU @2.40 GHz (8 CPUs)
    Intel HD Graphics 4600 1792 MB
    1TB HDD
    4 USB 3.0 ports, SD card slot, HDMI port, Headphone in/out, Ethernet port

    Tell me if my notebook is compatible, and also tell me what I need to buy and do if it will work at all. Thank you very much! :wink:

    We need the HP Part Number to find what exact model your asking about? Also ext graphics is not worth having or getting. If you want better graphics get a higher end system that has a dedicate GPU.

    Actualy it deepends on what you mean eGPU.
    If it just external GPU to connect an extra display - there are absolutely no problems to use USB-DVI adapter. This kind of eGPU doesn't support acceleration and use resources of your main GPU to accelerate graphics (note: even you have good GPU u might experience little lag on dynamic images as it cant transfer a lot of changes over USB -> you experience throttling/lag)
    If you want to connect GAMING eGPU - this is completely bad idea ... there are nothing good exists for this purpose. even you'll have 300W powerfull external GPU - you'll be limited by USB bandwidth A LOT. USB 3.0 bandwidth is about ~5GBit which is little above than 1xPCE 2.0 (3 GBit) or little less than 1xPCE 3.0(6 GBit)

    Note: your device probably have capability to install dedicated (internal) gpu of kind: GF740m or GF840m

    PS: even you can connect powerfull eGPU - you can benefit from it only in limited scenarios (e.g. intensive computations which requires a lot of computing power, but little data transfer)
