Iknow this question is better suited for year 2009 but my old Sapphire x1950 PRO while playing Assassins Creed(the original one) heats to above 90 degrees, that is 90° Celsius. Is that bad, I had it since 2008 and it still works. I even played some modern games like Borderland, Tomb Raider, Starcraft 2, Arkham Asylum without too without much problem though there were some crashes.
