I have the same model. Does it have the best performance for your buck ? No Will it end up obsolete and in the trash in a few years unless I find cheap parts

I have the same model. Does it have the best performance for your buck ? No Will it end up obsolete and in the trash in a few years unless I find cheap parts on AliExpress to have a laptop that holds together ? Hopefully, no either. Will I be able to upgrade to a more powerful motherboard or more RAM or a better SSD if I find performance is lacking ? or a better screen or longer lasting battery ? I already can.
