Fits, but not currently buyable as a set: 2× NVIDIA RTX A5000 (48 GB) needs 2 screened cards and the market has 1; 4× NVIDIA RTX A5000 (96 GB) needs 4 screened cards and the market has 1. We price a multi-card build from that many separate listings, so it stays unpriced until they exist.
- Our pick rows sit on top, then clean configs by price; cards with a caveat (cooling mod needed, or poor value for AI) group last, whatever their price. Watts and tokens/sec turn green or red when they sit far from this table's average (roughly 40% either way).
- Prices link straight to the screened eBay listing; hover for the seller summary. Seller details and the report option live on each card's own page.
- Configs without a screened purchase option are hidden until listings clear the trust screen (a multi-day survival window on eBay).
- Multi-card costs are the sum of that many separate screened listings; the cheapest listing counted twice is not a price anyone can pay. Prices exclude the PSU, board and case a multi-card build usually also needs.
- Tokens/sec are estimates, not benchmarks: spec-sheet memory bandwidth at 50% utilization divided by the model bytes read per token (how and why). Real speeds vary with the runtime and context length.
- Breakeven and verdict use default assumptions (40 h/mo, $0.16/kWh, 24-month horizon, resale at 65% of the going rate); adjust them in the calculator. Hardware links are screened, not guaranteed.
