2011 computer upgrade where to start?

[SamyBoy13]

Hello guys I'm looking to upgrade my computer but not sure where to start. I feel upgrading my cpu+mobo+ram would be the most rational option as the hardware is 11 years old. Yet is it really worth it? I play mainly single-player games Assassin's Creed, Forza, Red Dead Redemption, etc. (@1080p or 4k if settings above high +50fps) and that is occasional 1h-2h per week if that. The other thing is the pc is quite big as much as I like the way the CoolerMaster stormtrooper looks it is big so if it is worth upgrading my computer hardware this would be something I need to consider. Don't want to spend more than £400-500 plus what I can get for my hardware.

My current setup:
PC Specification:
I7 4770k 4.4ghz @1.262v Temps 60-70 Celcius degree under prime95
Asus Z87-PRO
G.SKILL RIPJAW 2133mhz 4x4gb
Asus GTX 1080ti Strix OC
Corsair AX760
Be quiet Dark Rock Pro 4
Cooler Master Strom Trooper case (Black)
