its not good. rather have 6 cores using 1.5a v 16cores. plus only thing u can use with 6 core is AMD opetron. and ive seen them processors in playchess and let me FILL YOU IN. they are very WEAK and slow vs a quadcore core i7 @ 3.5-4.5 GHz.
16 core opetron AMD = i7-920 @ 3.1 GHz. = sad.
intel Xeon x5680 6 core/12threads = i7-980x @ 3.33 GHz.
x2 amd opetron 32core total (16x2) server processor = i7-970 6 core/12 threads @ 3.22Ghz
