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.
Yeah that's pretty high. My new 560ti 2GB idles around 40-45*C. It used idle in the high 50's (and like 75-80*C in games) before I download EVGA's graphics card tool that has a basic fan profile that increases the speed as it gets hotter.
