+1 for Oland or maybe Cape Verde, small GCN ftw!
RX 550 i reckon is a bit too expensive atm.
8600 GTS or other midrange older cards might be interesting.
Personal bias would be towards something like midrange fermi or tesla (260,460,560) but with a restriction on no hawks/oc focused cards to try to grt people to be a bit more hands on.
All in all would love to see any form of a cheapaz renewal for 2022.
Oh, GT 220 maybe, for 2022 haha
