I'm planning to try to implement a eGPU over my PCIe 2.0.0 used by a Intel N-7260 Wireless adapter, which is capped at 2.5 Gb/ps. I checked using Sandra by SiSoftware. Will this be able to link to a external graphics card? And what problems can prevent this/block me from doing this? Such as the back-panel etc?
I know it's kinda dumb and very off, but I do not want to spend 400+ for a better PC/desktop, as they cannot be portable. I still want to make sure, or just be convinced not to do so, as I cannot be sure about it.
