Hello! I am new on this site but I decided to write because I need some advice coming from people who know things about PCs. Recently I have bought an office PC, at least that is what I think, but I really want an upgrade. I want to play a few games that are quite simple and old but that my PC can only run with low graphics. Therefore I want to buy a graphics card, preferably a cheap one, for around 50-100€. This situation creates two small problems: I do not know which graphics card I should choose and I also do not know if that specific card fits in my PC's case. I really want a decent upgrade for my PC and I hope that someone can help me with any kind of suggestion. I would like to attach a pdf. file with the description about the PC I bought but I do not know how.
