Zotac Refurbished Store
https://www.zotacstore.
It’s the best I’ve seen for price/performance if you’re just aching to replace a graphics card from 2016. All the GPUs are refurbished with 90-day warranties. The two refurbs I’ve bought from Zotac in the past are still both running after a couple of years.
RTX 2080 Ti Twin Fan $299.99
RTX 2080 AMP $239.99
RTX 2070 Blower Fan $179.99
RTX 2060 Twin Fan $119.99
GT 730 2GB DDR5 $27.99
This is what my wife’s desktop uses and I’ve played some old games on it just fine.
There are many other graphics card variants available, as well as GeForce 10 series cards. The GTX 1080 Ti price isn’t too bad. There’s also a $24 low-profile card.
