ITs perfect. Yes some people will tell you to pay more for the 3570K.. Thats pointless. Benches have shown gamers get no advantage with the 3570K over the 2500K.
I would say change the power supply though, the Corsair Gamer series are kind of ricey.http://www.newegg.com/Product/Product.aspx?Item=N82E16817139020
Love the NZXT Phantom btw, they're awesome cases.
