Buying gaming computer i5 4690 + r9 280x

[Rangojr]

Hi, so I'm upgrading from a crap laptop to much faster and more appropriate gaming computer. I'm having trouble not knowing what I'm looking for but I kind of have an idea. So I've been researching around for 5 days now and I've came across this site called pcpartpicker. So I've started to mess around and configure a gaming computer for around 800£ and I've came up with this. http://uk.pcpartpicker.com/p/yDYVZL any help would be appreciated. Also the game that il be running this most on would be Counter strike: go, arms 2 and 3 plus payday and some other steam games.
But mostly counter strike
Thanks, Alex

Thanks for your reply, but do you think that, that beast of a gpu would not overheat? Plus wouldn't i need to upgrade the motherboard? http://uk.pcpartpicker.com/p/8vP2ZL

everything on that list will work great the cpu you picked is not an overclocking board so no need for a super expensive mobo this would be a beast
