You can save 50$ on the CPU, tho the one I picked offers better performance and better OC capabilities. But you can go with the i5-4590, as well.
Also, if you're planning on OCing the CPU, you will probably need a better cooler than the stock one, so thats like 25-30 extra bucks.
However, if you give up the OC factor you can get a cheaper MoBo and CPU, it's up to you mate!
I can build you 2 setups to compare prices, one with OC capabilities and the other one without them.
