Hi, I’m a PhD candidate at Federal University of Rio de Janeiro and we are planning to buy a workstation to work with PLAXIS 3D available in the university. However, I have some concerns about the system requirements. The recommended processor is a Quad Core CPU. Nonetheless, I would like to know if there are other processors with more cores which improve the speed calculation? I have a similar doubt with regard to the graphic cards; the system requires discrete GPU with 1 GB of RAM, but I am wondering if better graphic Cards improves in some aspect the performance? Is it preferable invest only in RAM memory for larger projects than in CPU, Graphics Cards and RAM memory together?
