Z370 & i7 8700K

I would like to update my workstation with some newer hardware so I was thinking about I7 8700K since Iím using AE and C4D pretty much
where single core clock means a lot in everyday work.
Mainly I'm upgrading because of RAM, 32GB was not enough in few critical situations
For rendering I relay on Octane and Redshift so for GPU rendering I plan to
have 1x1080Ti (got it in current WS) and 2x1070 Sea Hawk Hybrids.
Got 3x780Ti which I'm going to put on external rig and attach them to WS via riser card.
Not rendering huge 3D scenes with huge number of textures, nothing heavy.
Would this be a good config:

CPU I7 8700K
MBO ASUS ROG Strix Z370-F Gaming
RAM 64GB (4x16GB) PC4-24000 3000MHz CL15 Corsair Vengeance LED red, CMU64GX4M4C3000C15R
SSD 2x 512GB Samsung 960 Pro (one for system/caches other for project files)
GPU1 Asus Strix GTX1080Ti Gaming (got it already)

Not sure what would be difference between this MBO and ASUS ROG Maximus X Hero,price difference is 90Ä.

Current config (which still serves very good) is:
CPU I7 4770K
MBO Asus Z87 Pro
GPU1 Asus Strix GTX1080Ti Gaming
GPU2/3/4 3x780Ti (2 of them on 1x risers)
SSD 2x 500GB Samsung 850 EVO

If someone got similar upgrade what is your experience on speed gain?
Is there some downside of this new architecture for GPU rendering?
Thank you.

Best regards,

The motherboard you picked isn't appropriate for 3 gpus. In general, the s1151 isn't the best choice for gpu rendering. 3 gpus and 2x nvme drives need more resources than the Intel's consumer socket can provide. If you really want to invest in this socket, due to the 8700k's top single threaded performance, then there is only one motherboard you could use, imo:

Imo, if you want to combine decent single core performance and enough pcie lanes for gpu rendering and nvme drives, then you should move to the 2066 socket.

Can you mention your budget? I'm sure there are some good alternatives for what you need.

You are right, I could sacrifice a little bit od one core speed for much better overall setup.
I think this could be a good base:

CPU i7 7820X
MBO MSI x299 XPower Gaming AC or ASUS ROG Strix X299-E Gaming
RAM 64GB (4x16GB) PC4-24000 3000MHz CL15 Corsair Vengeance LED red, CMU64GX4M4C3000C15R
SSD 2x 512GB Samsung 960 Pro (one for system/caches other for project files)

Is this speed of RAM ok, or should I go fro 8x8GB of faster RAM?I though to leave 4 RAM slots free and in future upgrade to 128GB if needed.
Thank you.

You're spending much money in nvme ssd's (especially the 960 Pro which is even more expensive) and I don't see the reason why.†

I asked you about your budget because I think you need to redistribute your budget in wiser choices. I wouldn't pick the MSI 1070 seahawk for a 3way gpu configuration. For the same price you can get a 1070Ti which would be faster in rendering with good temps and noise levels.

New GPUs will come later next year, if there is proper budget until then probably there will be new models
Now I just need to get new good base, CPU/MBO/RAM. New SSDs are also wait for proper budget.
Until there will be budget for new stuff I can make use of current components 1080Ti+3x780Ti and 2x500GB SSDs.

For the SSD I thought one for the system and caches (AE chashes, C4D/simulation chases) and other for project files.
From my experience in AE there is lot of time spent on retrieving files, so I thought SSDs with these 3-4x† faster read/write speeds would boost compositing workflow (hate waiting for previews )
Now I have 2x500GB Samsung 850 EVO. You think there l be no much practical workflow speed gain by getting those 3-4x faster SSDs?
Do you have better advice or some experience on this?

For 1070 Sea Hawk I thought it would be better choice because of cooling solution.
Price is pretty same as for 1070Ti† in my country and speed difference is small (Octanebench 119/130)
Other option is to invest in custom water cooling system for CPU/GPU, but then again I have to spend a lot on those components.
With Hybrid solution I could buy one by one in time as budget allows.

I would recommend waiting for couple months, because 8 core 16 threads Intel processor is going to launch replacing† i7 8700k and i am pretty sure z370 won't support that processor. And Ryzen 2 will also be launched replacing Ryzen, the same Ryzen motherboards will work though.
