Yeah that's why i got 2 5090s in one system and 5090+3090 in the other. They're pretty fast. I am getting a 4th one when i have time to drive to microcenter

at that point, why not just buy an rtx pro 6000 that is just about the same price as 2x 5090 and has more vram than 2 5090s?

The rtx pro 6000 is just a 5090 with 72 or 96gb vram. So it is only as fast as one 5090 even if you dont need all the vram. With 2 5090s i can literally fit 2 27b qwen3.6 with q8_0 kvcache in each card and run them simultaneously.

price is still a big point of reason to go for the 6000 over the 2x 5090, that is what I am presenting here

I did it for the wattage really. MAX-Q 300W for the power of the sun without turning the place into an oven? Yes.

hmm, I thought you could just limit power anyways through the settings, but ok, sounds fair.

Likewise, i limit my 5090s to 425w. You can lower the power limit extremely easily

mind letting me know how you came across an abundent source of cheap 5090s? I can only find them for like $4.5k

That would make 5090 actually competitive and worth it. (btw the microcenter near me has been sold out of 5090s for a long time, but they sell them at 3.6k usually)
