I've been planning on getting one and as of the end of November there were plenty to be had. The 4090D was going for around $13k.
Now, virtually all gone. In stores, carousell, price... Gone. I found one for $12k but it's btf design and would require a new expensive mb and new case. No thanks. The only other 4090 was 20K. Other than those 2 nothing. They all vanished so fast (probably as the 5090 leaks came out they went this route instead). With production stopped there won't be more.
So any other options I may have missed? Maybe missed few stores in ssp and mk, but certainly tried most.
