My 8800GT EVGA Superclocked is at Fedex right now so I can't really say...
But I can say that my 7800GTX idles at 50C and loads at 95C.
I had my fan accidently set down for a week or so it and would throttle itself when it hit 115C in C&C3. That was pretty noticeable =)
Anyways, its still had no ill-effects whatsoever... An XFX 7800GTX running at 515/1350 still like a top. Will make a nice card for my girl's photoshop rig.
I'm sure newer cars are ever so slightly more durable when it comes to heat.
I will say that card PCI slot placement and case airflow will make a huge difference in temps. Removing my TV-tuner results in a 20 degree LOWER load temp for my 7800GTX. So thats a 75C versus 95C.
