Worth upgrading?

I'm running i7 8700 with 16gb ram and a 8gb nvidia gfx card ( i dont remember the specific model) and it still running good.
I'd say your GFX card needs a update and if you can afford it a processor but the main thing would be the GFX card.. you have plenty of ram.
It will do pretty much anything you need it to do.

I guess if you got some spare cash to go upgrade than do it. If not maybe start with the GFX card but I'd say your still good for a bit.
