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.
Thanks, but you didn’t answer the question. Do you know for a certainty that this machine will even be used for graphics greater than downloading videos from YouTube for the first year?
My point is that ozaukeemom should purchase sufficient to meet the requirements (including video) but not hand off a high-end machine (unless they are made of money) as a first-time computer to what is quite likely a teenager.
