I'd definitly stick to the budget of £1k if self building, you can get all the nice internals + case, accessories and monitor for that and it will be alot cheaper than getting a prebuilt with the same specs.
The i5 is a good choice as it has good overclockability to around 4.79ghz depending on setup (not used the cooler mentioned above so can't comment on its effectiveness when OC'ing). To save cash to invest in the monitor, you can get 8gb of decent ram for £40. 16gb is overkill since most games don't utilise anywhere near that amount.
As for GPU, depends on you budget since both will handle modern games on high settings achiving above 50 fps easily (unless playing farcry!). The 7970 may have a longer life due to the extra number of cores, but in 2-3 years there will be newer technology out replacing both...
