It seems we are not on a same page here.
i3-530 is a 7 y old cpu that isnt made anymore, and its much weaker than NEW kabylake pentium g4560 socket 1151.
And g4560 wont bottleneck RX 470, it would however bottleneck card like RX 480 a little bit.
That pentium is essentially new i3, but half the price. Getting actual new i3 isnt worth it with this pentium around
