You'd want to get something like a RTX Pro 6000 (~ $8,500 - $10,000) or at least a RTX 5090 (~$3,000). That's the easiest thing to do or cluster of some lower-end GPUs. Or a DGX Spark (there are some better options by other manufacturers than just Nvidia) (~$3000).
Yes, I also considered the RTX 6000 Pro Max-Q, but it’s quite expensive and probably only makes sense if I can use it for other workloads as well. Interestingly, its price hasn’t gone up since last summer, here in Germany.
