I want to get a better GPU for my laptop but its soldered onto the board, I was wondering if I can just replace the motheroard with a different but more poweruful GPU, keep in mind my CPU, RAM, HDD, wifi card etc are all removable
I think a new laptop motherboard is going to cost you a lot more than you imagine.
You should search for the price before you get too far down this road.
I found some motherboards for my same laptop with a GTX 850m inside only difference is that it is blue but the laptop that it was inside looks exactly like mine
