liud21OP is trying to buy a 40$ card to get on the stepup, lol. The only cards that work are the ones ending in KR with a 3 year warranty, just make sure it's sold by a authorized retailer, and not some 3rd party that sells through Amazon....
basmith7just buy the new card
carbodWhy would you buy an old cheap card assuming you are stepping up to the 3080? You might as well buy a 2070 super. Either way you are paying the ~$810 or so combined, so why not just spend $500 now and enjoy a good card for a while and spend $300 later? It's better than buying a $200 card now and spending $600 later. Either way the cost is the same. Buy the best card now that is cheaper than the card you want to step up to.
