-Actually I think Joe's build is too expensive I mean, maybe is good but does not adjust to your budget so, The build I recommend is made to beat xbox one and ps4 this rig is made by: Pc Perspective
http://www.pcper.com/news/General-Tech/Video-How-Build-Gaming-PC-Beat-PlayStation-4-and-Xbox-One
it only include the cpu without anything else, no OS, mouse, keyboard, screen.
Our build below

As you can see in the Pc Perspective build they does not include the cpu cooler, instead they use the stock cpu fan, and they add 8Gb of ram and a 600w Power Supply Unit,
In my actuall build I included cpu cooler because the web page says I have to, that's why I select that one is cheap and has good performance, but you can skip it and use the stock one check the cpu temperature, if it gets too much heat then buy a cpu cooler and select only 4 Gb ram, and a 500W PSU, that's the actuall minimum to save some mony and goes well with r9 270x Graphic card, later you can upgrade to 8 Gb ram and maybe a 600w PSU in casu you lose some power but I think you will be fine
I could recommend a cheaper CPU but this one has a very good performance and it's great for gaming, image editing, internet browsing all at the same time, thanks to multiple cores
You will spend 517.20 on US + send & taxes depends of your contry termal paste, OS, mouse keyboard and maybe screen, you can use Tv with HDMI port
