External Graphics Card through PCI-e to USB

I have a laptop which is sufficient to play most games, except for one caveat: the graphics card. It's a GeForce 610M. I would be able to play most games on decent settings if I had a better graphics card, and I was wondering if it would be possible to buy some other nVidia graphics card, get a PCI-e (or PCI, I'm not sure which I'd need yet) to USB adapter and use the graphics card as a peripheral? It would massively improve my gaming experience.

Thanks!

  1. Not sure it would even work but if it did the USB bus doesn't have enough bandwidth it would bottleneck the card to the point of being worthless for gaming.

    Just as a theory, if I ran it through 2 USB ports would that help?
  4. Also, does dGPU mean discrete GPU?

    If you just want to connect it to a laptop you will need this:

    you will also need a power supply depending on what GPU your getting, this evga 400w will support all but 2 GPUs on the market(7990, r9 295x2)

    and you will need a monitor, 720p or 1080p is good enough but if you want 4k you can get it but its going to cost at least 4x as much and your going to need a really expensive GPU (at least $600 for a good experience) you can also use some normal display like an HD TV but not an old box tv with component connectors(red, white and yellow cables) if you dont have one just get this one:
