i use gpu z and everest which have given me identical readings or near enough try givng that a shot and see what temps you get.
also on a side note your g9800 gx2 is running extremely hot for idle and load
-do you have stock cooling?
-is it overclocked if so what clocks?
when i had my 9800 gx2 it was idling 45-50 or so and load was 70ish on about 80% fan speed constant
I have 3 case fans for exhaust, and my mobo, cpu and HDD are all mid-40's, its just the card that shows a big spike in heatmmm what kinda of case and ventilation u have set up as the gx2 does have a tendency to dump alot of heat into the case
