My GPU (GTX 670m) in my Asus g75vw turns up to 87 celsius when i'm playing SMITE, BF3, Crysis 3 and League of Legends. When i'm just surfing the web, listening to music or other simple tasks the GPU goes up to 47-50 celsius.
I don't really know the full name of the computer but i got it with a gtx670m, 8gb ram, 3d screen, 6x blu-ray, i7 3610qm and 750 gb HDD. (later on i bought a SSD and 8gb more ram to it)
EDIT: Just watched some youtube videos and now the GPU's temperature is 63 degrees
