This ebayer is selling several working 1660 Supers for a suspiciously low price (£72). Maybe he's dismantled an old mining rig, but still. They're selling for several times that elsewhere. I don't know if this helps you, but even if graphics card prices weren't artificially inflated, that would be a good price right now.
Condition is "Used". Not the cheaper and much slower 1660. Also, this 1660 Super OC is faster than my 1660ti by a considerable margin and also handles Raytracing (but not DLSS) with the latest drivers.
