I have a Dell Inspiron 15 7537, circa ~2014. I'm taking off for college soon, and I was contemplating whether I should invest in an entirely new build or just try to improve the one I have now (I want to keep the touchscreen and I'd like to save as much money as I can). In short, I was wondering whether I can replace the motherboard in my laptop, and then solder in a new processor, SSD, and RAM, and whether this would end up being cheaper than spending $1000 on a new laptop entirely.
