you need to burn in that card. since its a new card, the heat paste hasnt completely curred between the HSF assembly and the GPU itself. so play some games on it for a while, or just leave a game running with a 3d rendered scene and monitor the temps. 80c is a bit high as atomic said, but those cards do run hot. only at 90c would i begin to worry.
anyway, after running a few games the temps should drop a few degrees because of the breaking in process. all new cards need it, its usually overlooked but overtime your temps should drop a couple degrees. nothing major, just fyi.
