A SSD (solid state disk) instead of an HDD (hard disk drive)
allows clouds to load faster. As SSDs generally do not have a huge
capacity, it will be important to have additional storage, whether
that's a traditional HDD or just a storage/backup server.
As for processing power required, Point Cloud is a single-core
program so focus on buying a processor with more GHz, rather then
multiple cores. This means an i5 can be better than an i7 for less
money. AMD processors are fine too.
It is necessary to have a 64-bit operating system. Windows 7, 8,
8.1 or 10 are all fine but XP is no longer supported.
Point Cloud 2018 supports AutoCAD 2010 to 2018 (64 bit only) or use
IntelliCAD 8.3 which comes free with Carlson 2018.
It is recommended to have a separate graphics card, preferably nVidia GeForce.
