I think what Shroud wanted to say is "If you haven't bought it yet you might want to consider a more powerful Intel CPU+Z77 board in combination with the rest of your build" or something like that.
So yeah, I would also suggest you reconsider and get a i5-35700k and Z77 motherboard, perhaps a better power supply as well while you're at it. Unless of course you already have the components.
FX-4300 vs i5-3570k
I know yours is the FX-4170, FX-4300 uses less power and is clocked a little higher but it's still fine for comparison.
Edit: Just read the reply about winning it.
