Rendering can be a very interesting thing to do with a considerable amount of passion and knowledge of the software. But it is also necessary to have a system supportive of the specifications these software demands for smooth working. To enhance and magnify the quality of the content, updates and performance of the system are vital.
Below mentioned are the basic guideline one can refer to while quoting one specifically for rendering.
-Graphics card: Graphics Card scoring a G3DMark of 16,000 or higher.
-CPU: Intel/AMD Processor scoring a single thread CPUMark of 2500 or higher.
-System memory: 64 GB or more.
-Power supply: Minimum 80+ gold-rated with sufficient wattage.
-OS: Windows 10 64-bit.
3D Rendering will require a lot of cores & high core clock speeds, so AMD Ryzen 5, 7 series are good and thread rippers are best, for Intel go with i5/ i7/ i9 of 8th gen. or later, better if you buy Xeon CPUs. Pair it with a decent GPU like Nvidia Quadro P series or AMD Rx vega. Lots of memory is required to use 8-16Gb ram or more. For storage, M.2 are best or SSD for faster read and write. Lastly power it with a sufficient PSU as per requirement (600W minimum).
It is important to pick the best hardware of your budget, and this will require a lot of research on what you exactly need with the compatibility the system can offer for the smooth working of the list of software you will be using.
