building new PC, emulator CPU question

[fringle]

I just switched from an AMD FX 6300 to an i5 4670K and everything is faster. I had my fx over clocked to 4.5ghz and this i5 at 4.2 destroys it in every application, even at stock it was a lot faster then the overclocked AMD. I didn't have much of a problem emulating GC games with the AMD but wii games were for the most part more demanding and wouldn't run at full speed. Battlefield 4 for pc is said to use all cores of amd cpu's but I get better performance from the i5 then I ever did from the AMD. It would studder and jump around on ultra but with the i5 it's very smooth. Will never look at another AMD processor unless they get their act together and improve single threaded performance.
