I have laptop which has working Ethernet port but I always use WiFi . I am wondering if it is possible to run and use a graphics card (with external power supply) connected to the Ethernet port (with some kind of PCI emulation to emulate the Ethernet GPU as a PCI one).
A Cat6 cable can do 10 Gbps, which should be enough for a GPU to run and play games.
Could this be possible?

No.
Chances are very slim that your laptop has a 10 gigabit ethernet adaptor - its uncommon on high end desktops. You'd also need some clever hardware to translate between PCI-e to ethernet, and the latency, oh the latency. You have a device which is typically put as close to the processor as possible with 16 dedicated pci-e lanes right into it, and you'd be adding a ton of latency.
Such a device would essentially be a video card, plugged into a PC, rendering what you want to play on the video card, compressing it, and sending it over as video.
Newer laptops may be able to do this with thunderbolt, but that's a whole different protocol, with the necessary clever hardware available.
