Is it normal for a x1900 crossfire edition card to get up around 80-90 degrees Celcius during very high end game play at 660/765MHz. My card is stable and all, but it just seems hot for a graphics card. One thing that is deceiving to me is the fact that during high end play, I can exit the game window with Alt/Tab and then check the temperature really fast. I can see 90 degrees celcius but then see it drop 20 degrees celcius in 2 seconds. Is my temperature reading not right, or is my graphics card able to cool itself really, really fast? Also, this pertains to processors, I'm running at 2.55GHz on a Athlon 4200 dual core processor at 230x11 and during high end play it peaks at 62 degrees celcius. Is this a bad temperature for this processor, or should I go out and get a better processor cooling fan?
