Hello, decided to give a GTX 470 a go as eGPU (expresscard, EXP GDC, 8470p - 3320M - HD 4000) but i can't even install the drivers, when the GPU is plugged in, all animations on laptop screen lag. Like on the desktop mouse lags and system is very very very unresponsive. Every animation is very laggy and moving the mouse takes like 2 seconds before it even reacts, pressing any keys, same thing. I'm puzzled

It took about half hour to even make to the NVIDIA's driver installer to open up and roll the "Checking system compatibility" forever. If i unplug the expresscard cable from my laptop while it's on the desktop, everything is just normal. Same thing if i boot without eGPU.

I have tested with iGPU disabled/enabled = no luck, in safe mode = no luck. Also the GPU does not bother displaying anything on my external monitor while it's plugged in, but GPU is not dead, it's working and i have validated that on desktop PC. 

I'd like to know what i should do now? I had HD 4890 like few months ago working without any hiccups

Try to search the specific driver for the GPU. I'm using GTX 9600 and installing the latest drivers for an old card is not working.  try to search in Nvidia  website the specific card you have and it will give you the appropriate drivers.

Soon I will add my system & eGPU details or a build link to this my signature to give context to my posts

Nah, that did not help sadly. Same thing happened about 3/10 times when testing, sometimes it gave BSOD on boot about nvlddkm.sys and GPU did not even display anything on the screen...
