We currently have a PC with a i5-3470 16Gb RAM and 650Ti (1GB VRAM) and it is having speed issues working with models (particularly when the photo layer is on). We are looking at upgrading to a GTX1070 and cloning to an SSD, but before we go ahead I wanted to know if we are flogging a dead horse. My question is how heavy is Vectorworks on the CPU (not for rendering just designing work)?
