Anyone running 3 gpus? Looking for advice on best x670 that might be able to slot a third card on. (alien.top)

Currently have a msi x670 carbon motherboard with 4090/3090 combo on it that works well enough, but when tinkering with ai pain to have to close it at times when friends messing with bots or stable diff, want to load up a game so was thinking since I mostly just play stuff like rimworld or dota 2 lately and have a 7950x3d, i could get the thinnest 4060ti 16gb could get more vram for the larger models and could find and give up gaming on 4090 so could fit that on the bottom pci slot (its by far my biggest card)

https://rog.asus.com/uk/motherboards/rog-strix/rog-strix-x670e-e-gaming-wifi-model/ looking at this one thinking might be enough room for a middle slot card. Rest of pc is a 7950x3d/96 gig ram. I managed to get a small 3090 ( 2ish slot evga) that would fit on top slot. (The 4090 is like 4 slots in size. I also have most of bits to build a second pc but thinking for cost of new cpu/ram/mb i could try this option too since could sell the old mb for part of cost but does anyone know of any other mb options for 3 gpu.

(https://i.imgur.com/SWxUm5i.jpeg) Looks tight but i have fair bit of space below that 4090 that maybe could get enough space to fit another card between them, have gpus running at 60% power so never really get into high temp ranges.

4090 is 4 slot so has to go on bottom to fit in case. 3090 2 slot 4060 (or anything for gaming can go anywhere)

Thanks.

A graphics card of any kind won't fit in the bottom PCIe slot because of all the io connectors next to it. You need a riser yo use the bottom PCIe slot.

I'm more concerned about your psu lol. That said they make a riser card that has a stand for power supply as well to power the new card properly lol. Since you'll be having to go out of case for the airflow anyways, may be worth grabbing the $30 stand for the GPU
