temperature range

My XPS M1730 equipped with nVidia SLI 8700M GT and Intel(R) Core(TM)2 Duo CPU T7700 @ 2.40GHz. I installed a program to monitor the temperature of the CPU and GPU. It shows for normal usage: CPU 60 degree C, GPU 75 degree C, for games: CPU 70 degree C, GPU 90-95 degree C.

Is this normal for this video card model and CPU? What would the average temperature be?

Thanks
