What else should I pay attention to while swapping major components?
I bought a pre-built mid range PC in 2020 and it reached the point where it doesn't fit minimum recs in newest games.
I still haven't decided if I want to just make light upgrades or commit to a full rebuild, but while I understand how to pick a motherboard, GPU, CPU etc. I have no idea about thinks like PSU or cooling. What should I look for when deciding on "secondary" components?
Anyway, here's my PC. Is it even worth upgrading on, or should I just tear the bandaid off and build a new one from scratch?
Motherboard: ASUS Prime B360 Plus (DDR4, Socket 1151)
GPU: GTX 1660 Super 6GB
CPU: i5-9400f
RAM: 16 GB DDR4
