My machine uses an AMD Athlon 64 3800 and pretty much same type of temperature.
If you are thinking of overclocking it,,,you will need a really good cooling system for the cpu....once overclocked the temperature will jump and can cause ur system to be unstable.
Liquid cooling is best as it lowers the temperature down as much as possible...
If you have a bigger case with good air flow, that would be another suggestion.
I was able to overclock my 3800 from 2ghz to 2.5ghz..using liquid cooling, my case is pretty big as well.
