As of now, I have a Sapphire Radeon HD 7970 GHz edition (the Vapor-X) and never before have it hit temperatures over 65*C. Now, recently I started playing Assassin's Creed IV, and after that, It suddenly decided to rise up to 87*C (after approx 20 minutes)

Is this something I should worry about? Is it bad? Is it potentially damaging to my components?
