My proposed £550/$853.49 build

What does the forum think of this proposed build and what changes (if any) I should be making?

As shown in the spreadsheet £500/$775.90 is the perfect budget but that is hard to stick to so I have extended it to £550 or $853.49

 

Thanks for any help!

Everything is good, but there is this GPU OC version which costs just a few $ more :)

I have FX-6300, and stock cooler is not that loud as everybody says :) and on load keeps cpu temp ~ 49C, core temps ~53C.
