ACTUAL SYSTEM REQUIREMENTS
Below is a list of system requirements from TEAM FUSION SIMULATIONS (official developers) of the system requirements for the new Official Patch TF 4.5 update. It was taken from the ATAG forum as a reply to a question about system requirements. There is also the same list of System Requirements in a now updated Beginners Guide released by Team Fusion for the new Blitz Edition

I personally would go with an assumption that the system requirements from Steam are not accurate, and the one below should be a minimum you should aspire to to begin with in this flight sim. There are however people running the new Blitz Edition of CLoD with lesser specs.
My personal feeling is that although there is a specified amount of space in the system requirements for installation, the typical installation including TF's current patch is just over 8Gb. I'd imagine with mission files, temporary files and perhaps skin files being added, a large installation might swell to no more than 15Gb, so as long as you have that amount of space, you will be able to install without any problems."This system requirements list applies only to the latest upcoming TF4.5 update which will come into effect shortly
The current recommended system (as suggested by Team Fusion Simulations) which will run the game fine at normal resolutions (upto 1920x1080) on a single monitor with most settings on Maximum.
PROCESSOR: Core I5 3.2 ghz
GRAPHICS: NVidia GTX 960 2gb
SYSTEM MEMORY: 8 gb DDR3 RAM
STORAGE MEMORY: 250 gb Solid State Hard Drive for Operating sygame and system, backup 3tb SATA drive for storage
An optimum system would use a
PROCESSOR: Core I7 Quad core 4.0 Ghz, a
GRAPHICS: GTX 980 6Gb (or higher such as the 1060 upwards)
SYSTEM MEMORY: 16Gb DDR3 RAM.
CLOD cannot use more than 4 cores.
Unfortunately due to issues with the AMD cards, some experience land texture tiles being visible so for CloD Team Fusion recommend Nvidia cards. "
I would definitely recommend the use of an SSD Drive for Windows and Game installation. They really do make a difference to operating system loading time, game loading time and I'd imagine to gameplay as the game accesses files during flight. The minimum you will need will be 128Gb,
You can point most software to install on a secondary ordinary HDD drive and keep the SSD free for the OS and the gaming which will give you smoother gameplay.
