The used graphics card market is rather interesting. I can't tell, but it almost seems like bots and sellers are bidding on their own stuff. It's probably also the case that people are flipping them, as prices have increased quite a bit over the last month.
What I can tell is that the market is flooded with used 3060s, selling for over twice what they cost new. At the same time, the bargains are on the higher end 2000 series cards. Those are selling for a little less than their new price. The TI cards are still out of reach, but with a little luck you can pick up a 2080, for < $750 or so. 2070 Supers are about $100 less. Since their really seems to be no way to buy new cards, save for the old Ticketmaster model of camping out and rushing the door, that's probably as good as it gets for a while.
Looks like the 12th gen Intel chips are going to change the landscape a bit. They compete very well, or beat the comparable Ryzen chips, but bring a whole lot of new MOBO tech with them. I'm honestly not sure what the point of PCIe 5 is since PCIe 4 is barely being utilized, but streamlining the chipsets with DDR5 will certainly matter. In the end, though, I'm thinking it's a good time for a budget build with 11th gen architecture. The Intel 11 series was so poorly received, really only for not being newer tech, that a high end CPU and Z590 MoBo should come in pretty damned cheap in the coming weeks.
