Might as well buy 4 4090's at that price point.
Depends on your use case. The point of these is the software they are certified for and the driver support. That sort of software is so expensive the hardware isn't your worry. Also time is worth so much money at that point hardware cost doesn't matter either.
Very true + it would be a LOT faster, but for the iray rendering I do, if a scene exceeds 24Gb VRAM, it won't matter how many 4090s I have since it wouldn't fit on any of the cards and would just end up getting dropped to the cpu. So in a sense, you're paying extra for a much larger chunk of VRAM.
Plus I don't think there are any motherboards big enough with appropriately spaced slots to support 4x 4090s and the huge custom water cooling setup that would probably be needed to prevent too much heat from building up in the case. So we're stuck with having to buy more 2-slot workstation cards if we desire more CUDA cores for more speed and need 3-4 of them to fit on the same board without any space issues. This could be one of the possible reasons behind Nvidia making the gaming cards ridiculously huge & power hungry in comparison to their workstation cards.
Not really. The workstation cards have specific drivers and are certified for software that the desktop cards just aren't and nobody is going to use a desktop card for that stuff. The workstation cards are also clocked lower.
