I want to do this on a laptop as eGPU and the only port i have is x1 and considering it is on a laptop, motherboard replacement is not a solution. Is it worth it to buy a eGPU or it is better to go for a new laptop since this one has i7 4700mq, 16 gigs of 1600mhz ram but the gpu is gt745m which struggles at some games. Thank you for the answer and Happy New Year!
