I think what you should decide on now is what resolution you want to use.
If you want to use 4k resolution (3840x2160) then leaning more towards Lee's build may be worth it to have the two 1080s. If you want 1440p then one 1080 will be good now and for more hungry games in the next couple years one would hope.
To decide on the cooler for the cpu, think about if you want to watercool. If you want to get into that and spend a few hundred quid on a custom loop than a H110i would be a waste, get the cheaper one. If you don't think you'll watercool in the near future then by all means get the H110i, its a better cooler and much tidier in the case. (Your decision on resolution will probably affect this. If you want 4k, then you wont be able to afford a full custom loop immediately.)
As stulid said, to not have a m.2 nvme is a bit backwards. If your going to edit video then every little helps. and m.2 nvme is more than a little boost. You can add other drives to the main OS drive in the future if you dont want to buy them all now.
(By the way, if you take the second 1080 off my first build it is £2400 which is basically the same as the two new builds just posted.)
(Look like stulid as done a build while i typed this so now you have more decisions too
spending 3k is never easy)
