I got rid of this idea because the mobile gpu is faulty but I came across a modification that let you use desktop gpu on a laptop, it's available at a store in China I'm not just sure if it's going to be worth it or not. Thanks for the contributions guys 👍.
Yes this is actually possible and this device was created maybe like 10 years ago however nobody bought it because it would be a hassle to have to carry the device along with the GPU around with a laptop. You might as well get a PC in this case.
Then gaming laptops came out and this device had even less of a market. It also wasn’t cheap and you can only attach one GPU.
