glad to be of service
who needs an IQ anyway

anyway while there is no industry standard of what a CPU core is, they are really pushing the limits of the definition. With the new FX chips, it is 1 core and a fraction of another core and they call it 2 cores, because of this most of the resources are shared between the cores. with a true quad core, going from 1 core to 4 gives you almost a 4 fold increase while with the AMD FX solution, you get a little bit more than 2 cores of performance (but not quite 3 core performance compared to the phenom II x4
and from benchmarks, you are better off getting a phenom II x4 instead of a "quad core" FX CPU
if you look at benchmarks in mulththreaded tasks and the performance boost as more threads are used, you will see that with a true quad core CPU, each time another thread is added, you get a 99 to 100% performance boost, while with the FX, you may get around a 30-60% boost.
when the components needed for actual processing are being shared, then the load on one core will impact the performance of another while with a true multicore (where no processing components are shared), 1 core can offer it's full performance to 1 thread while another core can offer it's full performance to another thread.
tomshardware did many reviews on this and have stated the same thing as to why the FX chips give lower per core performance
