My gaming laptop recently stopped being able to run FPS games without freezing. I am looking to finally upgrade to a PC, but I have no idea what I would need. I am looking for a middle-of-the-line PC that is cost-effective and can run for like 5 years without needing to update it. To clarify for rule 4, I need to know how to build without having a drastically overpowered piece held back by the rest of my pc, therefore wasting money.
