The components seem good for ArchiCAD 16.
You can also check it yourself against the official hardware requirements:

If you are using many other program like you said, I would seriously consider buying at least 16 GB of RAM (this is based on my own experience - I also like to use many programs at the same time without having to close them). It is probably the most important component in your system as if your CPU is a bit slower, so what, but if you run out of memory, your whole system slows down dramatically.
