Best performance core for budget

[TheZarke]

Which core would give the best gaming performance (assuming everything else is roughly equal):
i5 4570 + GTX 760
i3 4130 + GTX 770
FX-6300 + GTX 760
FX-8350 + GTX 770

In short, should I spend more on cpu or gpu?

for mostly gaming, FX-8350 + GTX 770 is best combination and if you have more budget, then spend more on gpu because it is hard to tell when you will get bottlenecked with this cpu
