What CPU is right for me ?

Hi, I have researched around Google for 5 days into weather or not to get the new Gen of Intel's new CPU's. I may self was looking at getting the i5 3570k with a 770GTX, But the new gen has came out with the new i5 4570k haswell CPU.

To my understanding there's nothing different between them except for the power wattage and the heat.
I don't want to do wrong in building my first system, I would like it to last.


So to round this all up Is it worth getting the new Haswell CPU or Go for the 3rd gen CPU's (i5 3570k)

Thanks! Build list (4570k) http://pcpartpicker.com/p/142rg (3570k) http://pcpartpicker.com/user/Ram/saved/1IFn

Any suggestion will help :)
