This is a quote from XFX about a HD7970
"The normal temperature range of a video card is up to 95C under load. We
expect that in most cases a card will not break the high 80s but large cards
under high load can get as hot as 95C.
This temperature will not damage your video card and is considered normal.
If you need to check the temperature of your video card then we
recommend using GPU]Z from http://www.techpowerup.com/gpuz/"
Why is it deemed ok to run GPU`s at high temps for long periods of time and frowned upon at CPU at this temp. The architecture may be completely different, but i thought the biggest fear was Silicon Migration with to much heat over time.

"In this paper, we analyzed the performance of an important set
of throughput computing kernels on Intel Core i7-960 and Nvidia
GTX280. We show that CPUs and GPUs are much closer in performance
(2.5X) than the previously reported orders of magnitude difference."
So why the big difference in operating temps taking into consideration the new high-end GPU and CPU may be even closer in performance.
