Motherboard recommendation

[Xander Cousins]

So here is my problem,

 

I have an i9 12900k cpu

x3 M.2 SSD's

a GPU (x16)

A Capture card (x4)

 

 

I have the problem which I require to upgrade the motherboard to have the GPU be able to use its PCIE x16 lanes

While allowing the Capture card to use its x8 lanes without causing issue from to or from the x3 M.2 

 

My current mobo which is running an i7 11700 has that limitation if I wanna use my Capture card at the moment It down my gpu pcie to x8 

 

As the lane it use to connect to is disabled due to the M.2 requiring to disable that lane, 

 

 

So In short I need assistance with ensuring all components listed above can be used without issue or limitations from on another.

 

 

And if able to brownie points for someone that can find a mono that can do the above but x2 GPU's instead.

 

 

I would search around but I honestly dunno what I would be looking for or reading for in regards to this problem,

 

 

Thank you in advance :D

There are a lot of boards that should do what you want. The two off the top of my head are the Z690 Unify (X) and Z690 Carbon, both from MSI, but others do exist that should do everything you want

Need to look at the block diagrams for each motherboard. Gigabyte is very good about documenting the PCIe layout.

Z690 aorus master is the way to go IMO for 12th or 13th gen...

And how would you know if an addition to that pcie lane causes that slot to go down from x16 to lower?

the main x16 lane? You can tell because it is hooked directly to the CPU - no switches involved. So no matter what devices you put into other slots, it will not change. 

Take for instance the Z790 aorus master - there are switches involved if you use the M.2 gen 5 slot and it will cut the GPU PCIe slot down to x8. Just one of the many reasons that the 690 board is better than the 790 board in this instance.

So if it shows a connection in the diagram via switch, it will show the cut in performance or usage of that lane?

Right- its hard to see in the diagram but the word "or" is present between those options.
