Question Motherboard for Dual RTX 3090 + Extra Card

Looking to build a dual GPU setup with two RTX 3090s plus a Titan Ridge card. That's two triple slot cards and one single slot card.

Does anyone know a motherboard that could accommodate that? Seems like most boards out there would end up physically blocking the third PCIe slot, if two triple slot cards are installed.

PCIe 4.0 would be ideal. Titan Ridge requires a Thunderbolt connector on the motherboard, too.

(Also, if anyone thinks this is a bad idea, please tell me! I'm not looking to build a gaming device -- it'll be used for crunching numbers)

Cheers!

Welcome to the forums, newcomer!

You would need to narrow it down to either boards with a TB port on the board or with wide spacings. You might even have to look at a prior generation motherboard to accommodate those cards.

Do you have any preference towards AMD or Intel...? If you do, it might impede your progress for finding a board.

Hi!

Yeah, I think you're right. Finding a board with integrated TB plus DP Input looks like a better way forward. Gigabyte B550 Vision D seems to be reasonably close to everything I need, although I'm a bit concerned about how close near each other the two GPUs would be.
