Swapping to pc, need help with parts and in general what they do (gaming)

Hey, my name is TJ and im a 15 year old console gamer, soon to be a pc gamer. The thing is im kind of a pc newb and i need your insight! Please could you suggest ideas and components for my build and what the parts do! Thanks! And btw my price range is around about 1500-2500 gbp and i will be wanting to run max settings on games like bf4:) much love!

GBP soooo UK right?


Well you could put it in dollars, i could convert it back into pounds:)

Wasn't sure if you needed peripherals or whatnot...
