Hi,
Here's a quote from X-Bit Labs who reviewed the XFX 8800 GTS...
"The GPU temperature varies from 47-58°C in idle mode to 85-86°C under heavy load in 3D applications. These showings are acceptable for the G92. The card has no effect on the temperature of other system components because the hot air is driven out of the system case."
As for your Processor, I see no reason to worry about it's temps. It is not that high and can also be controlled by AMD's Cool'n'Quiet Technology, if you have that enabled.
Here's a link to the Cool'n'Quiet resources webpage......
