Decent deal on RTX 3080 20GB on ebay - $30 per GB

So as I was shopping for extra 3090s, I noticed a seller listing RTX 3080 with 20GB VRAM for $600. I decided to message them about the import tax and I didn't realize they handle it. So the price on their ebay page is the price you pay for the item. No import tax.
I took a gamble and bought 2 of them, and they actually work! They ship from China so it took a few weeks to get here, but it was worth it.
From a cost perspective it's the best I found for VRAM ($30/GB). That's about $15 LESS per GB of VRAM compared to the 3090. The mem bandwidth is \~750GB/s (about 200 less than 3090), but it's still a really good deal for supported CUDA GPUs.
Keep in mind these also require 2x 8PIN PCIE PSU cables, just like the 3090.
For the price of 2x 3090 you can get 80 GB of VRAM with a little less mem bandwidth, I think that's a fair trade!

What’s the noise level like on these?

Surprisingly not high. The fan style does seem to be for servers, but I have them outside of my DELL R730 with a PCIE riser cable and I cut holes in the top of the case. I didn't notice them much. I definitely won't trust having them in the same room AND outside the case. If these were in a 2U server, they wouldn't be too loud.

This week I noticed that Alibaba has RTX 4080 with 32GB VRAM, just over $1000.
Ebay has them for $1900+.
I never ordered anything from Alibaba yet. Trying to figure that out.

I would give it a shot. In terms of per GB cost, it's roughly the same, but the 4080 is newer; supported longer and may be a bit faster on PP. I went the ebay route just because it's easier.
