Are these components good?

[NvidiaHelpPlz]

My plan was to build a semi-good gaming computer, and my budget was 900 dollars.... This is what I got, and I would like to ask, that are these reasonable components, and would you prefer something else for me to get...

Get better ram if you need overclocking. Something like a 2666MHz.

But i suggest give up overclocking. Then you will be able to get a better graphics card.

Or you can get the RX 480 when it comes and get an i7 6700. You will save some money this way.
