Build Advice New graphic design/gaming computer (buy parts in Japan) ?

[sLiKi]

Fellow Tom's Hardware comunity,

My actual system is giving me already a lot of headaches (i7-5820K+X99S+970 G1 + 970 M2 SSD 500GB + 16GB RAM (4x4)) and soon I will be in Japan for a few weeks.
I think, considering that the prices there are considerably lower than in Europe, it is a good opportunity to build a new PC.

I will mainly spend the computer for gaming, but I'm doing time to time graphic design in After Effects and Photoshop. (Right now, I need insane hours to render pretty much anything, and after effects throotle a lot during previsualizations)
I'm not sure I'll buy all components at once and haven't set a budget yet, but I'm willing to go on the medium-high quality way.
I'd appreciate recommendations specially on the CPU, and Motherboard, I can suppose the rest of the components (RAM, PSU, Cooling, etc)

Sound card and so it's not important, I have a Focusrite Scarlett on my build.

CPUS:
I've been watching the 5700X, 5800X ; But was told to switch to Intel, I suppose the 12700K and the 13700K are their relevant ones. Opinions?

MB: (Looking for a motherboard with 2x M2 4.0 at least to place a decent memory set for after effects)
Here's where i'm quite competely lost right now.

Be kind and help me figure out the best array, then I'll share with you some pictures when it's built
Have a nice day

What's your budget and what country in Europe are you located?

For motherboard + CPU around 600-700€, but can spend more.
the i7 5820K lasted almost 8 years, I'm expecting to replace it with another timeproof computer.

Thank you very much for the input.
I have already a RM750i, and for cooling I was expecting to re-spend also my Kraken x61 which is still keeping my CPU at 28º at iddle and 42º at load.

For the GPU, I will spend my 970 G1 untill nvidia release the 4080, 4070 and 4060, then take a decision but at the moment.
