Hello I just resetted my old laptop and I'm curious if it would be worth it to make some changes. I'm not really sure whether I want to upgrade some components or not and I can't really find what the possibilities are. It's a HP Pavilion g6-2201sd. My question is: Is it worth it to upgrade some of its components? (For example, 4gb ram -> 8gb, add a ssd (if possible), change processor)
