Rendering 3D objects and scenery of course requires even more graphics grunt and benefits from higher-end graphics chips. While performance components get the headlines they are not the only consideration for video and 3D rendering. These machines should be quiet, take no more space than needed, look good in the workspace and have components that are reliable. For example, having a middle of the road power supply is OK for gaming sessions that last a few hours at a time. Where the off visual artifact or glitch goes unnoticed. When rendering a 30 or 40 hour job however, these are problems you canít afford and thatís why these machines are built with a different eye for priorities.
