Your system can still perform decently at this moment (if it is still working a.k.a not yet broken or facing instability issues).
Your system is a bit old but not yet ancient and not really out of date.
I think your system is still OK.
You can try considering an SSD for an update, and OC your system.
See my system for reference, it should have about the same age as yours (except for the SSD, PSU and GPU), I plan to get a new proc, mobo and ram somewhere next year, during sommer or perhaps later.
