My suggestion is to add more cores and install a graphic card with more memory and more Cuda cores - RAM is more than enough (for archicad I mean). I dont' know which software you are going to use to make rendering ... but You'll need CPU cores (in case of use of CPU calculation renderers) or GPU Cuda cores + Graphic memory (in case of use of GPU calculation renderers)
