Do you know what the requirements and specifications are?
Requirements for working with graphics? Two words: very high.
You need a fast CPU to process the calculations necessary to render the graphics (some high-end workstations have multiple CPUs installed, a configuration known as Symmetrical Multi-Processing, aka SMP), a large amount of RAM to handle the temporary storage of those graphics, a spacious hard drive to handle the permanent storage of those graphics, and a GPU that can handle the rendering the applications all demand.
