How can I upgrade to... perhaps i7-6700K & GTX 1070?

Dear Anyone more knowledgeable/experienced than I,

I have a several-yrs-old desktop, HP Pavilion HPE450f:
Chipset = H57
CPU = i7-870 @2.93-3.6GHz
GPU = Radeon HD5770
OS = Win 7 Home Premium 64-bit

Over time, for purposes of photography & some multitasking, I have upgraded to:
RAM = 16GB DDR3 max
SSD OS drive & scratch disks
and some little PCI & USB peripherals

With my computer gradually losing a little speed/responsiveness/performance, as programs become more complex, I would like to upgrade what I believe to be the most significant weak links in my system.. the CPU & GPU. But, every few hours in my research/education on the matter, I seem to uncover new challenges/obstacles.

My fantasy was that I might just plop in a new CPU & GPU. But, it seems that my motherboard can't handle that. And then my case MIGHT not be able to handle the new mobo. So, now, I'm getting swamped in various configurations of CPU + GPU + mobo + case. And the newest challenge.. maybe Windows 7 can't handle that?! (AND maybe I need a dedicated CPU cooler, as well?)

What would you do in my shoes?
-i7-7700K looked like a good upgrade, but then not for Windows 7, so I started thinking about i7-6700K.
-GTX 1070 seems to present no problems.
-Do I need to care about Z170 vs Z270 mobo?
-Do I NEED a CPU cooler?
-How can I make this process as non-invasive as possible and keep Windows 7?.. And, is it true that I may not be able to just connect my currently-in-use hard drives (with OS, programs, and data) into this new mobo-CPU-GPU assembly and have Windows 7 and everything else just pick up and go?
-And RAM.. will it be possible to keep my DDR3 RAM for the time being? Would it be possible to upgrade to something like 24GB (because I sometimes bump up against my current 16, but I wouldn't like to spend money for 32GB if I don't need it)?
(I expected, of course, to spend some money, but I am already surprised by how much... GPUs are more expensive than I expected, and I didn't expect that I might have to replace the mobo, and, probably, the case. Money is an object. That's why I'm trying to make piecemeal improvements, rather than just buying a new computer [and I also dislike waste, and I like things to be customized for my needs]).
-And, while I don't yet have the math, I understand that I might have to upgrade the 460W PSU.

What can I do?

Thanks, In Advance!
 
well if you are going for the New CPU say I7-6700K its a overclocking CPU hence you need a Overclocking bpoard too say z270 and overclocking produce heat so you need CPU cooler too and your old DDR3 ram will not work in it you need the DDR4 Ram and if you are gonna fit GTX1070 in it then i recommend you to go for atleast of 600W psu to be on the safe side so that it will power everything in your case

:) Thanks, Nitinvaid.. you've given me some confirmation that this is like a cascade, where one change leads to another.

The specific advice about the DDR4 is helpful.

And the specific advice about the z270 is helpful. I wasn't PLANNING on overclocking, although, in doing my research, it seems like a common thing to do-- and maybe even wasteful of a CPU's potential to NOT overclock (when done within safe limits). It sounds like you are implying that z170 mobo would not be good for this, and that the only extra hardware I may need for OC is CPU cooling, correct?
 

Yes you need a CPU cooler then if you gonna overclock it
