Because of the video processing is not understood, here mainly refers to the use of premier shear film, do AE. The best thing to do is to give up what you want with the price down.
Video processing is a considerable consumption of CPU resources process, in the video processing there are many different formats of video file playback, is a real-time decoding process, and video processing inside the rendering, is a coding process, all of these are CPU real-time calculation to you.
So, you want to do video processing, such as splicing, synthesis (Final cut,ae), you had better configure a powerful CPU, this should not be weak, otherwise all interview.
The second comparison consumes hardware resources is the hard drive transmission rate, if there is raid, or SSD is better, otherwise you have to use SATA hard drive.
The third is the memory space, in short, the bigger the better.
In fact, the graphics card is not so important, unless your premiere video processing There are some OpenGL or DirectX real-time effects, otherwise the graphics card only processing two-dimensional pixel display. Even if you need the video card real-time effects, and not the type of high-end special effects of the game, the graphics requirements are not very high.
