In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries.
Graphics card temperatures typically range from 30c to 40c at idle and from 60c to 85c under load. Most high end video cards typically have a maximum temperature between 95c 105C, at which point the system will shut off to prevent damage. A video card is not considered to be overheating until it exceeds 90c under load. At this point, artifacting may start to occur up to the point of thermal shutdown.
Walker said that the GTX 460 does not generate much heat. The graphics card draws up to 150 watts of power, according to the company. The card will likely compete on price with Advanced Micro Devices' ATI Radeon HD 5830, which was priced under $250 on launch, but is now priced at $199 on retail sites like Newegg.
