This is a pretty good build, which is approximately £700 (this was put together from black friday prices, so I assume it'll be the same as hardware is less expensive in the UK)
I mean you could add another 8GB ram, upgrade the CPU to a 1600X and the GPU to a 1070?
Gotta upgrade the PSU aswell then.
Answer a few questions so we can point you in the right direction..
Do you have a monitor currently? If yes, what kind of monitor is it?
Do you have a color scheme? If yes, what is it?
Do you have a previous build that may have some decent parts? If yes, what parts?
Do you plan on overclocking?
