Whats better a amd phemon x4 or fx 6100 or 4100 for gaming
An AMD Phenom II x4 840 processor is weaker than both the FX-4100 and FX-6100 processors. Also, FX-4100 performs identical to FX-6100 in gaming so buying FX-6100 is not a good move. Therefore, between these three, the FX-4100 is overall better, delivering good performance and better overclocking potential.
If you do not plan to overclock your CPU, then I think you should go with the Intel Core i3 2100 because this processor performs a little better in games when compared to the non-overclocked FX-4100 and FX-6100 CPUs.
