Yours might be a bit outdated, but for small sized projects it should work fine. Mine is even older and still works even on medium sized projects (although I am about to change it in a few days). If you plan on using the new redshift rendering engine you may have problems though, as the requirements for that one seem to be very high in terms graphic card requirements.
A ssd based system & Archicad installation is good, a nvme would be even better (go and fetch a PCIe card for that, if you don't have a nvme slot on the mortherboard). 32Gb ram should be enough if you don't have many different programs running at the same time, but the more you have, the better everything will work. Your CPU is a 4 cores 8 threads one running up to 3.5 GHz, which is, as said, enough for smaller projects. It might even work with medium sized ones, depending on the level of complexity your project model will be developed to.
