Help with a gaming build!

[Ksvirdi]

Guys, I am so clueless on where to begin and I want to buy a gaming PC this summer with a budget of £800, with no OS, I don't know where to begin I mean I have tried out the configurator for myself but am unsure. The games I will play are BF3, cod4, CSGO and F12013 or 2014 when It comes out of course..

Any help is truly appreciated..

Do you need a monitor, keyboard & mouse?
With a budget of £800 it's crucial to know that in order to make a system suggestion.
