CPU usage has nothing to do with the CPU strength.
Then can you tell me what CPU usage is?
CPU usage indicates how hard the CPU is running.the percentage refers to how much of the individual CPU’s capacity is in use, and from Wikipedia
is the amount of time for which a central processing unit (CPU) was used for processing instructions of a computer program.
CPU strength refers to the CPU power, how fast the CPU doing the calculations and processing to PC programs and it differs from CPU to another depending on the architecture.
By current do you mean the FX processor's?
Actually i said the current x6 series, i meant the 1000T Thuban family, but even after FX released and benches showed that the Thuban is better in most gaming scenarios...technically the "Deneb" should be over the "Zambezi" as Phenom II 980 BE did better than FX 8150 in some games.
