Because of how dependent on GPU performance the point cloud building step in PhotoScan is, the best way to reduce the time to generate a 3D model is to utilize more GPUs. Balance between the number of CPU cores and GPUs is critical in PhotoScan, though, so this system also includes higher core count CPUs than the dual GPU configuration. This larger tower system has room for up to three GPUs, and the added space inside the chassis also allows for more drives and higher amounts of RAM. Here is a chart from Agisoft showing their memory recommendations. You can also take a look at our PhotoScan Recommended Hardware section for more information. If you are still unsure what specifications will best meet your needs, please contact our consultants so we can answer your questions and guide you to the right system.
