The benchmarks don't make for particularly good reading for the AMD FX 4100 Black Edition.
Sure the multi-threaded application performance shows improvements over the equivalently-priced Intel Core i3 2100 Sandy Bridge CPU, but the single-core and gaming performance is rather poor.
That said the Bulldozer FX 4100 processor does overclock, which sadly the Intel chip cannot.
