Depends on your definition of budget friendly, I suppose. I was looking around the other day and the cheapest working 24GB RTX 3090 on eBay was $1800 CAD after exchange rate, shipping and all the rest.
Hugely inflated from the $700 they were once going for. Maybe there are still deals around.
This seems quite unlikely. What motherboard are you getting three 16x GPUs on? That alone with the associated sever processor would be more than a used 3090, before even buying the three 3060s. Give full BOM and costs.
