New build budget

[Jaahmin]

Well I am starting my first build, but I have been given so many recommendations I'm starting to confuse my self xD I'm looking for a first gaming PC that will last a while for a budget of £650 give or take. I would need it to be wireless too. I'll use a Form used in one of the post's to help you.
System Usage from Most to Least Important: mostly gaming, movies and anything else
Are you buying a monitor: No
Parts to Upgrade: none brand new system
Do you need to buy OS: Yes
Preferred Websites: Whatever is cheapest but legit site
Location: City, State/Region, Country - Midlands, UK
Parts Preferences: I would like intel or whatever is better for gaming.
Overclocking: Maybe
SLI or Crossfire: Maybe
Additional Comments: I would be able to play next gen games
And Most Importantly, I am upgrading because my laptop can't play higher demanding games and switched from xbox360

Any help will be appreciated
Thanks.
