So I've decided to upgrade my Alienware 18 laptop's GPU from two 765m's to a 980m, as well as the RAM it has from 8GB to 16GB. I already have what specific upgrades I want to purchase, but I want to be sure I know what I'm doing with them. Is there a link to a tutorial on how to upgrade my RAM and GPU for my specific model, or does the model not matter that much? Either way, is there a link for a tutorial on how to upgrade my RAM and GPU? I just want to make sure I know how to actually install the hardware and not screw anything up.
