A $5,000 workstation centres on the RTX 5090 (32 GB, 1,792 GB/s).
| Part | Choice | Price / what to check |
|---|---|---|
| GPU | GeForce RTX 5090 (32 GB) | $1,999 launch MSRP |
| CPU | Current 6–8 core desktop CPU | Any recent 6–8 core chip is enough; LLM speed depends on the GPU |
| Motherboard | Matching socket | A budget board is fine; check PCIe x16 slot |
| RAM | 32 GB DDR5 | Two sticks for dual-channel; see RAM prices |
| Storage | 1–2 TB NVMe SSD | A Q4 70B model file is ≈40 GB; leave room for several models |
| PSU | Per GPU maker's recommendation | Use the wattage on the GPU maker's spec page |
| Case | Fits GPU length/thickness | Check the case's max GPU length against the card |
Only GPU prices are cited (NVIDIA launch MSRP). Other parts are listed with what to check rather than a price, because we do not yet track live prices; the total may differ from the headline budget. Target example: Qwen3 32B at Q4 needs ≈23 GB.
