Solved! Asus Rog Strix gl553vd

Solution
Not worth it at all, you may be able to use a mini PCIe external adapter but would be a waste since it will only run at PCIe 1x speeds and will bottleneck the video card. Plus you would need the adapter, the card, a power supply and a monitor attached to the system. Clunky and not effective.

If you want a faster laptop, sell yours and buy one with a faster video card.
