Question [Need Suggestion] Regarding new x870e Motherboards.

[Zaselim]

Hello everyone,
So 9800x3d is coming and i want to upgrade on it. What i am getting confused about is with lane sharing on the motherboards with gpu and m.2 slots.
I have rtx4090 and i may sell it to get 5090 when it releases, depends on the performance gap.
So what i want is to be able to use full x16 lanes for my GPU and at least 4x m.2 gen4 ssds and at least 4xSata HDDs either with sata ports or with sata expansion card. My current board has 7 sata slots and i am using 6 drives with it (2xssds and 4 hdds) and my current board has 1 m.2 (its a gen3 drive for OS and games). So i will be transferring this m.2 to the new board and will be getting 3xgen4 m.2 drives. Also want connect my current 4xhdds as well, dont care about the 2xsata ssd drives i have.
I will appreciate the help in suggesting with which motherboard can i go for all that i want/require. I originally wanted to go with Asus Rog strix x870e E-Gaming but it uses lane sharing with both pci-e slots and with m.2 slots so its a no go.
Thanks.

I'm curious to learn what you do with your system that requires all those PCIe4.0 SSD's. That being said, you can look at this board;

ProArt X870E-CREATOR WIFI - Tech Specs｜Motherboards｜ASUS Global

Built for creators, ProArt X870E-Creator WiFi features ASUS AI technologies, PCIe® 5.0, DDR5 slots, dual USB4®, 10 Gb & 2.5 Gb LAN, WiFi 7 and four M.2 slots

www.asus.com

You did however forget to mention how much you intend to spend on your motherboard, where you're located(since product availability will vary according to region) and your preferred site for purchase(if you're located outside the USA). I'm assuming you have an ATX chassis.

Sorry, yes availability does matter. And i can spend at around the price of asus crossfire x870e hero (699 if i am not wrong i can go as high as 800usd). I do 3d modeling (characters/cloths/architectures etc for games and animations as a job and work on 3ds max, blender, Daz Studio, Marvelous Design, UE4/5, Premier, Photoshop as well as some music production work. Plus i also game (4k/RT/PP level quality) and i don't want to lose too much performance on either (work/gaming) sides, a little bit is fine.
Actually i have 5 HDDs (8tbx4 + 4tb) and 2 sata SSDs(500gb each) and 1xm.2 gen3 (2tb), i have a lot of data (assets) and i do only use it daily but i may need them any day so i need to have it on my PC. My blender/daz/3dsmax/MD data alone is around 8+Tb. Then Project (save) files (from 500mb to 2gb per file) are on another drive around at 2+tb currently. And my video files (not backups but the ones i use regularly) are on another drive is around 15tb which is why i can't go external because of low speed. My 4tb drive is only for downloading (games, videos, songs, etc files which later I move to their specific drives). I am not saying i will need all of the m.2 at the same time. First i am only gonna buy 2xgen4 (4tb each, 8tb drives are too expensive like 800 to 900+usd which is why i need 4 of them) drives. Which makes them 3 (1st my current 2tb gen3 only for OS and programs minus my 3d apps like UE5/Blender etc), and 2nd 4xgen4 4tb for games and 3rd 4xgen4 for my 3d related stuff to load data/assets/(which i used daily and regularly) and project files faster. I may need another down the line or may not but i want to be safe/sure to have the option for 4th drive.
And like i said i have 5 hdds and i also want them in my system internally or at least 4 of them and most boards we have today have 4 sata slots so my save bet is to go with expansion which may share the pcie lane which is also a problem so i need to use on board all 4 sata ports for at least 4 hdds.
I have Corsair Graphite 780t Chasis (Full tower ATX).

The board you mentioned has same issue as x860e egaming and crossfire x879e hero.
Can't use 4 m.2 slots without sharing pcie lanes.
M.2_2 and M.2_3 makes pcie from 16 to 8 lanes, and pro art has no gen5 pcie support (for gpus) but e gaming and hero has pcie 5 gen support bit same issue, can't even use 2 or 3 m.2 ports with sata ports. And using 4 m.2 slots makes gen5 pcie x16 to x8 (gpu).
The only board i could find was Asrock phantom gaming x870e Nova and we don't have asrock boards support here. So if i want one then i will have to import it with customs/duty like charges and it will also have no local warranty coverage and i will have to ship it incase of warranty which will cost more money. So i can only use local availabile brands which are Asus, MSI and Gigabyte. My whole reason for going amd this gen was that I read/heard they didn't have the pcie lane sharing problem on there side like intel boards have. But apparently they do now.
