I have recently bought a Dell G3 3579 laptop with Intel i5 and a GTX 1050. Just a few days ago, I saw one of my friends with an identical looking laptop, another G3 3579, but that one had an Intel i7 and a GTX 1050Ti. So, is it possible to desolder the i5 processor from my motherboard and place an i7 processor or change my graphics card with a Ti? Not asking if its economical or practical cause I am confident that it isn't, only asking if its possible.
