70-80c is a bit hot, is that stock cooling you are running?
@ Sub - see my last post, i have run 3dmark
@ guru - Stock voltage.
@ Phoenix - From what info i have gathered 70-80C isnt that high.
Anything more than 65c for c2d is pretty hot, usually good temps are about 50-60c for full load when OCed.
I think some of the previous AMDs and p4s runned pretty hot around 70c, cant remember really but I wouldn't put more than 65-66c on c2d.
