I change some pc components.
1) RAM, you don't want to buy two individual sticks, because they may or may not work with each other. You need buy the Kit RAM like 2x4GB, 2X8GB, because the manufacturer test them to make sure they work. If you use the PC for games, 8GB will be more than enough. But if you still want to 16GB then get this one.

2) HDD, you want to get the 7200rpm, not the 5400rpm that is only good for storage. you are better to use the 7200rpm for OS.
3) PSU, reason: cheaper but still good for the r9 270x, the GPU requires 500w but I add more wattage for headroom.

4) I add a cpu cooler and the better MB, you can easy to OC to 4.0+Ghz with the asus M5A97 R2.0, and the cpu cooler keep the cpu temp down, because the AMD cpu is easy to cool down, so I pick the cheaper one usually I will recommend hyper 212evo.
BF4 cpu/GPU performance

If you buy those cpu+Mb combo. you can save some, but I still recommend to get fx6300+m5a97 r2.0
Here is my list.
