At about $2,000 a 16 GB RTX 5070 Ti or 5080 gives more bandwidth than the 5060 Ti; for more VRAM, consider a used 24 GB card.
| Part | Choice | Price / what to check |
|---|---|---|
| GPU | GeForce RTX 5070 Ti (16 GB) | $749 launch MSRP |
| GPU | GeForce RTX 5080 (16 GB) | $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, two x16-size slots | Check slot spacing for two cards and x8/x8 lane support |
| 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: gpt-oss-20b (MoE) at Q4 needs ≈14 GB.
