I took a fair amount of time to get everything to a reduced power level and measured several llm models (and hashcat for the extreme) to find the best speed per watt, which is usally around 1700-1900 mhz or limiting 3060 to 100 to 115 watt.
If I planned it in the first run, I may got away with a used mac studio, thats right. However, I incrementally added more cards as I moved further into exploration.
I didn't wanted to confront someone, but it looks like you either show of 4x 4090 or you keep silent
