I’m not very tech savvy so please bear with me.
I bought a premade in 2018 and I’ve only updated the graphics card and ram since then. I’m using a 55" Samsung TV as a monitor. It’s really starting to get sluggish/finicky. Gaming example: it can run BGate3 on medium but starts having issues any higher.

Any new parts are most likely going to necessitate a complete rebuild. Your mainboard probably tops out at PCI3, a new GPU will be PCI4. It’ll work, but you won’t see as big an improvement as you expect. Any new CPU is going to need a new mainboard because intel. New mainboard means upgrading to DDR5 RAM because that’s the standard now.
Alternatively go the secondhand route, you should be able to pick up an i5 or i7 that’s socket compatible for not much.
