# Used GeForce RTX 3090 24GB (business sellers only)

**The Budget Workhorse — 24GB under $1,000** — DealCoconut researched pick in AI Inference Hardware
Canonical page: https://www.dealcoconut.com/p/used-3090.html

- Current price: $925.00 (MSRP $1,499.00)
- Known low: $800.00 (market floor)
- Buy timing: **Fair price** — Prices rose all year and won't fall while VRAM demand rages — but don't overpay past ~$1,050; at that point a 7900 XTX new (~$900) deserves the comparison.
- Reliability: **3/5** — It's used, mining-era silicon with no manufacturer warranty — the honest 3/5. Manage the risk: buy ONLY from established business sellers with 30-day+ returns and real stock (our standing rule — never one-off listings), expect to repaste and check thermal pads, and stress-test within the return window.
- Price note: typical used market $800–1,050 as of 2026-07 — climbed all year

**Why this pick:** The community-standard budget inference card for good reason: 24GB VRAM and 936 GB/s run 32B-class models fully on-card at roughly 87% of a 4090's inference speed, for well under $1,000. And it stacks: two cards = 48GB = 70B Q4 at genuinely usable speeds.

**What it beat:** New RTX 5060 Ti 16GB (~$450: the VRAM ceiling walls you out of the models worth running) and 4060-class cards (bandwidth-starved for this job).

**Cheaper alternative:** This IS the save-money pick. Below it, run small models (8B) on whatever GPU you have.

## Common questions
- Two-card setups — x8/x8 PCIe 4.0 is fine for inference (splitting layers/tensors needs little bus bandwidth); 350W each, so 1200W+ PSU, and power-limit to ~280W for ~5% loss and much less heat.
- Skip NVLink — llama.cpp/exllama don't meaningfully benefit; save the $200 bridge money.
- Software support? — Full CUDA support, still first-class in every inference stack. Ampere isn't going anywhere for years.
- eBay safely — business sellers, 1,000+ feedback, quantity listings, 30-day returns. Test hard in week one: memtest_vulkan, sustained load, all 24GB touched.
