APPs to monitor the temps of my CPU and GPU !?!?

hey guys what do you recomend ? and could you tell me the normal temps at idel and full capacity and also the save range of these temps of SAPPHIRE RADEON HD 6850 and AMD PHENOM IIX4 960 ????(both the CPU and GPU are at stock settings didn't overclock )

playing games skyrim , assasins creed , battkefield 2 , metro 2033 and mass effect (and yeah im a bit behind on gaming but trasitioned frm my ancient PS2 )

Hwmonitor, GPUz or speccy do the trick. And temps all depend on ambinent air temp, case and airflow.
