Without k , you can't do that
Your Phenom is pretty old indeed . Since Dolphin is a dual core application , Pretty much any low end CPU (like Pentium Haswell G3220) can blow it out of the water
i5 4670k + MSI Z87 G45 are your best bet (keep in mind that only Z87 mobo support OC)
i3 4130 @ 3.4GHz isn't bad at all . It's faster than FX 8350 @ 5GHz in Dolphin Benchmark
It's almost twice as fast as your current CPU in Dolphin performance
i3 is a non k CPU , it can't be OCed so you can pair it with H81 mobo
i5 4570 is just a bit faster than i3 4130 in Dolphin and so do i5 4670 . I had to choose an i5 , I would get an unlocked version rather than a normal one
