That's a fun comparison, but can you run those 2 m5 pros in parallel to accomplish 2x the work? Otherwise, you just told me you can buy 2 toyota corollas for the price of 1 F-150 while trying to convince me you can haul your boat behind both corollas at the same time.
All I'm saying is that the comparison doesn't make sense. The 5090 is faster on a small subset of tasks if attached to a computer which ends up being 3x the price of a m5 machine that fit the same model or the same price as a machine that fits models 5x bigger
So you're saying that buying 2 Corollas for the cost of 1 Ferrari engine would be better? Even though the Ferrari engine is much more powerful, it's useless without the rest of the car.
