If under full load i would say that somewhat normal.
Still, a bit on the hot side. For most modern GPUs, 70ish C under a full load is considered normal.
I would Prefer mid-low 60s MAX myself ...
beyond what thefabe has suggested, perhaps try and get some better airflow to the card.
if your seeing 74C and 50% fanspeed at idle however, then theres a major problem
As far as whats "normal" .... Its hard to say exactly. has it always run that hot? If so, then its likely that is normal for your card.
I would still try some of the measures suggested to cool it off regardless
