1st for games currently released will be decent for 1080p.
3rd if you plan on keeping the gpu, games slated for the Q4 2018 are more than likely going to tax even a 1060/6 at 1080p as games like farcry 5 do now.
3rd one, but the newer 2600X would be a better choice if you can get it - just bear in mind older motherboards would need a BIOS update.
If you wanted to go intel go and can't afford to go with an 8600K + 1070 then get an 8400 + 1070. Forget the 7700, while it is a good gamer buying a 4 core CPU now that there are all these 6 and 8 core options feels like the wrong choice to me. The 8400 is just better.
Edit: also you can use a cheaper motherboard with the non-k intel CPUs which gives you more money for the GPU.
My thoughts basically summarise to:- any 6 or 8 core ryzen or i5/i7, 16GB of RAM, any reasonable motherboard that is compatible, and the best graphics card you can afford
Zen + 1070 all day, even at 1080p, if you max out quality details and crank up AA. Steam just released a hardware survey showing AMD nearly doubling their percentage on processors being used for gamers. Very impressive. They are only getting started at chipping away at Intel for gaming.
