If you look at various forums, e.g.
http://www.sapphiretech.com/en/forums/archive/index.php/t-38.html
other people have reported similar temperatures for similar models,
though as one person notes:

my x850xt pe runs at 70 under full load, whitch isnt overheating...but
if its crashing then it may be to hot for that card...do you have any
third party programs (like ATI Tray Tool) to show you the fan speed
settings? Mine were set extremly low from the factory...didnt go up to
100 percent fan untill 98 degrees :eek:

So if there's some way to alter the fan settings, you might want to do that :)
Also, how crowded is the video card in his computer?
I note on http://www.thetechzone.com/?m=show&id=197&page=2 regarding
the x800 that "The card is designed for a single slot PCI-Express, so
it does not come with a hefty chip cooler. There are no heat sinks or
heat spreaders for the memory, which would have been nice if they
included them." which to me sounds like the card would have a tendency
to get warm, especially if there's not enough good airflow around it.
