I overclock my AMD Athlon X2 4800+ CPU to 5200+, clock speed increased by 10%, from original 2500GHz to 2750 GHz, and now the temperature is 75-79oC, is it too hot?

As can be seen when looking at the link posted by repo (post #2) the safe max temperature is 55-68 C, which is a lot lower then the 75-85 C range you talk about. Your CPU will be able to handle high temperatures for a short (!) time, but it will eventually go wrong.
Either stop over-clocking or add/replace cooling to get rid of the access heat.
now I only increased the overclocking by 5%, it cools to 65-70oC.
And you're still in the danger zone.
Although I get the feeling you don't really care about what the specs, repo and I are telling you, I am going to warn you once more: Constantly running at these temperatures will put a high strain on your CPU and it will take its toll. Is putting your box at risk worth the 5% increase?
That said: It is your box and you can do whatever you want to do with it
Why exactly did you overclock that cpu ? Just asking because the performance advantage of a 5% overclocked cpu is only recognizable with special benchmark programs. On the other hand you are buying this little performance burst with reduced cpu lifetime and an additional source of error. I wouldn't recommend it on a desktop that's being used for work.
The whole overclocking scene has imho become a pure marketing gag. People are buying heavily overprized "overclockable" boards, ram, cases with special "airflow strategy" etc. when they could just buy the next better cpu/graphics card and probably get away cheaper. But ok, that's offtopic :P
