My collection is far smaller than most folks in this thread. 😉 I'll create a CSV-styled list with a similar fashion of my list of computers:
1990, new, ISA, some unknown monochrome display adapter that came with DTK 80386DX-20 (probably also made by DTK), recycled.
1992, new, ISA, Triplex ET4000/w32 enabling VGA graphics on that DTK 80386DX-20, recycled.
1995, new, PCI, Number Nine 9FX Motion 771 (S3 Vision968) that came with Dell XPS Pentium 120, recycled.
1996, new, PCI, S3 Trio64V2/DX 1MB by Top Solution Technology (TST) that came with custom Pentium-MMX 166, inactive (currently my oldest functioning PCI graphics card).
1999, new, AGP, STB Velocity 4400 (Nvidia RIVA TNT 16MB) that came with Quantex P2-400, recycled.
2000, new, PCI, Gainward CARDEXpert SG4 Savage4 Pro 16MB, active in TXP4 + Pentium-MMX 233 (my fastest PCI graphics card).
2002, new, AGP, PixelView GeForce3 Ti200 replacing Velocity 4400, overheated and died after its cooling fan malfunctioned.
2003, new, AGP, GeForce4 Ti 4200 64MB came with Alienware Athlon XP 2200+, recycled (I wouldn't just throw away this card; probably faulty).
2006-7, hand-me-down, AGP, Asus N7600GS/HTD/256M, inactive (and couple capacitors are bulging; I'd rather go digging from e-waste than replacing its capacitors).
2008, new, AGP, ATI Radeon HD 3650, either recycled due to faulty or hidden somewhere in my parents' (I'll try to remember confirming its existence in my next visit).
Circa 2011, e-waste, ISA, Trident TVGA8900D 1MB that came with MiTAC Am486DX2-50, inactive (currently my only working ISA card).
2016, new, PCIe, Asus GT720-SL-1GD3 (OEM) that came with VivoPC K31CD (i5-6400), active.
2018, auctioned, PCIe, Asus EN210 Silent 1GD3 that came with C2Q Q8300, active.
2018, new, PCIe, Zotac GTX 1060 AMP Core Edition 3GB, active in my main working computer (H370 HD3 + i7-8700).
2019, auctioned, AGP, Asus N6200/TD/128M/A that came with GA-K8VM800M + Sempron 2800, recycled due to bulging capacitors and very unstable performance (froze the system while idling).
2020, auctioned, AGP, Gigabyte GV-R9000 Pro II, active in GA-6VXC7-4X-P + P3-800.
2020, e-waste, PCI, S3 Trio64V2/DX 2MB that came with Asus TXP4, active in Dell XPS.
2021, hand-me-down, PCIe, Asus EN210 Silent 1GD3 that came with Gigabyte GA-P31-ES3G, inactive.
2021, e-waste, PCIe, PowerColor AX6450 2GBK3-SH, inactive.
2021, e-waste, PCIe, Asus EAH5670/DI/1GD5, active in GA-P31-ES3G.
2021, auctioned, AGP, Gigabyte GV-R96P256D, active in K8V-MX.
2021, e-waste, AGP, Asus V7100PRO/64M (GeForce2 MX 400), inactive.
2021, e-waste, AGP, Asus V9560XT/TD 128MB (GeForce FX 5600 XT), active in Asus A7V133-C.
Inactive: 6 (or 7, if HD 3650 still exist)
Recycled: 8 (or 7, if HD 3650 still exist)
