It depends, I'm not sure if it's a binning thing and they can't make enough perfect chips for the 3090. Or it might just be limited memory, they're using all the gddr7 that's being made and that's with many different suppliers.
I've been trying to get a 5090, refreshed eight stores for a while. I saw one 5090, that you could purchase, 3200€, gone instantly. It's now the "topseller".
Two shops list the different 5090 models, none available of course, two others had 5080s for a while, before removing the listings again, although they supposedly weren't sold out.
I was lucky to snag a PNY 5080 but this looks like the tightest launch since the 3080. Maybe worse. Supply chain analysis suggests we’re going to see a lot more stock in the coming months so no one should feel left out.
honestly just any chain that sells lets say all the components necessary to build your own rig and like soldering stuff. Like everything computer and electronics related one could think of. I don't really care about tvs or appliances but definately want laptops and monitors.
