Graphic workstation suitable for post-photography

When it comes to photography, we should first consider the color problem. The monitor must be professional (expensive), and it is best to equip it with screen calibration equipment, which is available online. The computer itself is almost ok, but it affects the speed. Now the mainstream is completely enough. The memory and hard disk should be larger, and the speed of memory can be faster. The hard disk is bigger because the original file of the picture is bigger and takes up more space!
