I have an fx 8320 and the same MoBo that you have selected. The motherboard is fantastic, well spaced out, easy to set up and install plus I've had no issues with it whatsoever.
Could you give us some more details on your build? I.e are you building this from scratch or do you have existing parts? Do you need an OS and if so is that part of the £600 budget? Then we'll be able to offer you more help
