We don't necessarily have any recommended PC requirements anymore, as pretty much all Windows 10+ computers nowadays have sufficient memory, etc. SSD hard drives are extremely efficient and preferred for FAB. The best performance for FAB 3000 however is on Linux 64-bit.
Note: In mid-2023 we will be offering a Lightning Mode option in FAB 3000 for extreme performance gains. Essentially Lightning Mode assigns multiple processes simultaneously to perform a specific task and pools their memory.
