Any advice and edits are welcome. My budget cannot really go over £1550

The second build. The better GPU will give higher FPS at 4K and both CPUs will be bottlenecked by the GPU. So better to get the 1080TI and the 1600 than the 1080 and the 1700.

However i did a small change to give you a much better PSU for just around £5-6 more. Whit a high end system like this, you don't wanna go cheap on the PSU, specially if you are going to overclock the CPU. Also you don't need 750w.
