You have the right idea, but some components should not be considered at all and here is why.
Your spending about $200 on your crappy FX CPU and liquid cooler. You could be getting a much better haswell i5 for less. Skip the liquid cooling and the FX CPU. Also your spending $100 on a motherboard you don't need. Your memory is fine. All 8gb 1600 kits will be pretty much the same. Your Hard Drive, Case and PSU are complete garbage. Get rid of them and don't look back. Your GPU is fine, but you could be getting a much better one.
Here is what I would recommend for about $840. I know its a little on the high side, but its definitely worth it!

Your getting a powerful Haswell i5 which will perform exceptional in gaming. I also through in a basic B85 motherboard that will cover your needs. I through in 8gb of DDR3 1600 memory. As I said before it doesn't really matter the brand you choose. I don't think you'll be needing a full terabyte so I switched it to a cheaper and better 500gb Seagate Drive.
The graphics card is now the EVGA GTX 760. Phenomenal card at a great price! Great cooler on it btw. I switched the case to my favourite budget case...the Corsair 200r. At $30 you can't go wrong I added a 550w 80+ gold haswell compatible power supply. Its made by the best brand(Seasonic) and it will cover your needs with plenty of room to spare.
I hope this helped you. Let me know if you have any questions or comments.
