It depends on the chipset you're talking about. Generally newer cards can go up to about 80 degrees celcius and remain safe. I'd say anything 70 degrees or below and you're fine. Oh and you're perfectly fine with your temperature dropping when you're out of the game. That's a good thing really since the graphics card isn't rendering anything to the display whilst you're tabbed out.
