PC Requirement for GIS Software

If you visit ESRI Website for PC Configuration for GIS, you Get much lower requirements. But actually thet are written as "minimum to run" Means that only to run software not to process. For processing large data you need High End PC, otherwise your processor burn for long term use and procession of GIS software. Normally if your image is more than 4GB it take large amount of time to process, you cannot process whole state or country. If command given it take couple of hours or end with insufficient memory error. So here is PC Requirement if you are going to Build desktop or thinking about laptop. Model or made of pc does not matter, its configuration just matter.

Best PC Requirement for GIS Software.

Sr.No	Component	Specification	Remarks
1	Processor	i7 or whichever Higher while you reading it	Recommended more then 3.0Ghz
2	HDD or SSD	HDD is not recommended for large process environment. Use SSD instead of HDD	Because SSD has no moving part and having write speed of 1TB/s and HDD has just 30mb/s
4	RAM Minimum 16gb	2300 or more mhz	DDR4 or 5
5	Graphic Card	Nvidia GTX	More than 4GB GDDR5 or more.
6	Screen	As you wish	Large more than 25 is Recommended
7	Mouse	Mouse with DPI Adjustment	Required for more accuracy during digitation
