What would be smart on the financial side as a student?

I am looking to buy a new gaming pc as my current one has reached the end of its life. So while looking on used marketplaces I found a few different options, I wont go into details but lets just say that one is a bit older, bit dated parts and will not last me 4/5 years, but it is cheaper option at €350. Then there is the other option which has newer parts that still have warranty, is very new(august 2024) and will probably last for around 7 years till it starts to become old, that one is around €600. I was wondering what the best choice would be on this. For context: I am almost 18 years old and will have to start paying insurance monthly, I am also a student. I have a job that pays me good enough, but I dont work often because of football(or soccer) training. Which option would be the smartest on the financial side of things?
