Anything below 85C is safe temp and well within the specs for the R9 280X
the card itself will hit thermal limits at 95C and will throttle the card. Running the card at temps 90C and higher for extended periods of time will shorten the life of the card.
OP your card is fine as 76-80C is well within the specs laid out by AMD, as long as you stay below 85C you should get many years out of that card.
If you want to make sure the card runs cooler you could try adding another case fan on the side blowing on your card which will probably drop temps by 3-4C and in turn make your fans on the card run much slower.

"Here in his shrine, that they have forgotten. Here do we toil, that we might remember. By night we reclaim, what by day was stolen. Far from ourselves, he grows ever near to us. Our eyes once were blinded, now through him do we see. Our hands once were idle, now through them does he speak. And when the world shall listen, and when the world shall see, and when the world remembers, that world will cease to be. - Miraak
