Hey I think it mostly depends on what you’re working on. Right any programs and game engines has minimal specifications and recommended.
The minimal are required to open this engine and reserve it on your system hardware but if you want more fps and no lags you need better hardware than recommended. As I said before it depends on what you’re working, the example third person character or first person will use less memory hardware than almost finished game via unreal editor, because it may use too many assets in content browser and everything that exist on the world outliner, plus blueprint data with other classes.
On my project with my PC I get 80fps while largest map/level is loaded but when I started from scratch I get 180-200fps. The graphic settings of editor was basically High with high textures, and I never used cinematic.
If you’re hobbyist, just speed clock to 3.2GHz (not 3.4) and remember about good cooling for this cpu
