eBay Graphics/Video Cards, used RTX 4090 asking prices

Live SRP capture read 2026-10-03 (used-only filter, 60 per page). Depth is real - the Used facet was populated and the page returned ~50 used consumer cards. This is the cleanest public read on USED GeForce pricing. Price buckets: under $1,400 / $1,400-$2,800 / over $2,800. Brand facet counts: ASUS 292, MSI 254, NVIDIA 250, EVGA 192, GIGABYTE 192, ZOTAC 122, PNY 42. IMPORTANT TRAP OBSERVED IN THE DATA: the used-4090 result set contains a large cluster of listings that are NOT 4090s at all - water coolers ($239.99-$435.00), 'heatsink and PCB (no GPU)' parts ($239.99), and ASUS ROG XG Mobile eGPU docks with 16GB, not 24GB. Anyone scraping 'cheapest used 4090' off this page without reading titles gets a cooler. Real used 4090 24GB cards cluster at $2,000-$3,000.
