according to this it is a dual core processor. i am not sure why there are 2 
for each core. i would err on the high side and choose the highest temp for 
each core to display. the thermistor is usually under the processor at least 
on my mobo it is, and so itis subject to nearby component heating as well and 
not as accurate as the core temp readings.

don't know haven't really looked for it since i have the cpu temp displayed in 
the bottom window bar of each core.

the number of processes running, number of users and the system load average 
if you choose to display that.

i don't know on nvidia chipsets, i can only assume a sensor module is missing 
to be able to sense these things. are you using lm-sensors? if so from a 
terminal session what does the command 'sensors' return to you? it should 
show everything readable by the current modules.
