It's hard to answer Yes or No
If you want a straight answer : No , it's too weak for most games , light-weight games are playable though . If you want more games to be playable , you will have to overclock (Recommend : 4.4GHz). Keep in mind that all current AMD CPU have poor single threaded performance . Since Dolphin is a dual core application , FX-6300 @ 4.5GHz stand no chance against the outdated i5 2400 @ 3.4GHz in Dolphin and i5 2400 is slower than i3 4130 @ 3.4GHz which cost about the same price as FX 6300
See Dolphin Benchmark
The recommended CPU for demanding games is i5 4670k , not i3 4130 though...
However it's all boil down to your experience in the end , not "FX-6300 is good enough for you or not" but rather "Can you deal with slowdown , audio stuttering or not"
