Does anything in my system need upgraded?

[Efblair]

I built a high-end PC in June 2014 for somewhere up from a £1000, and it is still running well, but I was wondering if anything needs upgraded at the moment and if not, when should i start thinking of upgrading? my specs are:
Motherboard: Z87-G45 Gaming
RAM: 16GB (cannot for the life of me remember the make)
CPU: Intel I7 4770K
Graphics Card: AMD R9 290x
(if you need to know anything else, ask away)

I doubt anything would need upgraded at the moment, but it's nice to have a second opinion and the knowledge of when i should upgraded so i can keep some money aside, thank you
