Woo, that's a little bit on the high side. I think there was another member on here that had a 6800 video card with high temps too. Maybe they're suppose to run that high? Not sure on that. All the cards I've owned in the past has always been around 40's-50's celsius range. It shoots up to crazy 70's, 80's for games.
I wonder if the ambient temp from within your case is warm? That will affect your GPU temps too. Then again, you're still within safe temperature range.
