PCI card spacing

[kurama3114]

Hello, I am planning to build a pretty overkill gaming/streaming system on Z390 with two 3-slot GPUs (ROG Matrix) in NVlink, an Elgato capture card, and an audio card. This is obviously a very tall order to fill and probably not possible, but I was wondering if anybody was aware of an E-ATX motherboard that would be able to fit all of these expansion cards while still giving the GPU's room to breathe.

Swap the audio card for an external amp+dac, it'll give you some more room .

 

Also, when ltt did this they used the MSI Z390 godlike to get the spacing needed.

That sounds like it would work, and the Godlike motherboard was one of my top candidates. I'm not a pro on pc audio, but I am already planning on getting Yamaha's MG10XU channel mixer/audio controller for my mic as well as outputs. Would this completely replace the need for an audio expansion card in the pc?

I'm not certain on sound stuff, so I can't tell you for sure.

I have elected to just not use a soundcard and just have the 2 graphics cards and the capture card. Now I am wondering which slots each should go on. I couldn't find the official specs for the graphics card (It was just announced recently) but I'm guessing they are about 55-60mm thick, which would mean they would extend over the slot below. With this in mind, would it be smart to have the graphics cards on the 2nd and 4th slots with the capture card on the 1st, or in some other configuration.

As much space between the GPUs as possible is ideal, the capture card wouldn't block much airflow if it's between the cards.
