how hot can video card get
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.
