Does anyone know a good system monitoring app that works with an asus p4p800-e? I cant find the one that asus offers.

Well, what do you want to monitor?
CPUZ: CPU frequency/motherboard info
CoreTemp: CPU Temp
Everest: General PC info/temps
OCCT, Prime95, Orthos: Overclock checking
RivaTuner: GPU temps/fan speed/other info

I am overclocking my celeron 1.7GHz and I want to monitor temprature mainly... I tried the Core Temp but When I ran the program it said my CPU isn't Intel architecture...
