Old School

I'm looking to grab a cheap card for some old school COD2, CS:GO at max 1080p. Looking to spend $60 maxish? Any ideas? Should I look for older cards? I have no issues buying used. Won't play that often and I'm not too picky as I've been playing using Intel Hd 1000 graphics.

Folks have varying definitions of "old school". Are you talking AGP or PCIe? What are/were the recommended (not minimum) specs for the game?

Old school refers to the games I'd like to play ie COD 2,etc....Pcie because regardless what the oldest games recommend, I'd like to play some newer games here and there.
