Do you need any peripherals at all?

BIG FAT STINKING EDIT:
I didn't realise that the previous comments were 2 years old so excuse the slight biggotry, I thought everyone was being silly. Apologies.

Why are you all recommending the GTX 970 when the RX 480 outperforms it for £100 less.
Also he can go with a sky/kaby lake cpu and fit in budget.
You're all crazy.

OP I beg that you ignore the previous comments and go with a build more like:

monitor supports free sync.

Better yet, if you can go over budget by 50-100 you'll be able to pick up a gtx 1070, however, in that case I recommend changing screen as no need for free sync. g-sync monitors cost a lot so I'd recommend going with something basic (maybe a 2ms 1080p screen and then upgrading to a gysnc monitor when you have £200+ to spare)

Reasons not to go for the other builds listed:

i5 7500 > i5 4690k on base performance, you didn't list whether you wanted to OC but i'm gonna assume no for now. Otherwise I recommend the i5 6600k or i5 7600k, both of which still stay well within your budget.

RX 480 > GTX 970 on [strike]pretty much[/strike] literally all benchmarks

DDR4 2400 RAM supported on mobo, however, if you want to get a better mobo and get some 2700-3000 ddr4 ram instead, that's another way to fill your 1000 budget

Newer intel chipset, alternatively, you can wait for AMD's new Ryzen line to be released, which looks amazing in comparison.

Unless you're SLI/crossfire'ing or have a titan and an i7, you're never gonna go above the recommended power levels for an 80+ gold psu at 600 watts alone, the extra 50watts is just to be safe. Some of the people here are recommending 700 watts+, lol for what? If it's because the PSUs they listed are fully modular then you can just get a 600-650 watt fulyl modular psu for £20 less, still. Wasted money on overdoing it unless you have plans to SLI/Crossfire (as said)

Case is purely preference, you have enough budget left over for whatever case and additional case fans you need.

M.2 SSD >>>>>>> Sata SSD, if you want to go a step further you can get a PCI-E ssd (supported on mobo I picked), 1tb hdd is standard back up.

After market fan not needed less you're OC'ing
