Frequently asked questions
How much does a local AI PC cost in 2026?
A usable starter build with a used RTX 3060 12GB lands under $500 and runs 7–8B models. The sweet spot is $1,000–1,300 — an RTX 4060 Ti 16GB build or a used RTX 3090 24GB build — which covers 14–32B models. Around $2,400–2,900 (RTX 4090 or dual RTX 3090) you can run 70B-class models at Q4.
What's the cheapest way to run a 70B model locally?
Two paths: a dual used RTX 3090 build (~$2,900, 48GB pooled VRAM, fastest) or a 128GB unified-memory mini-PC like the Beelink GTR9 Pro (~$1,899) — cheaper and silent, but roughly a quarter of the token speed because of its 256 GB/s memory bandwidth.
Mini-PC vs building your own for local AI — which is better?
DIY wins on speed per dollar: discrete GPUs have 3–7× the memory bandwidth of unified-memory boxes. Mini-PCs win on capacity per dollar, noise, and convenience — a 128GB Strix Halo box fits 70B+ models that no consumer GPU can hold. Buy DIY for interactive speed, mini-PC for big-model capacity or a quiet office.
Is a used RTX 3090 still worth it in 2026?
Yes — at ~$650–750 used it remains the best VRAM per dollar. 24GB runs 32B models at Q4 fully in VRAM, and its 936 GB/s bandwidth is close to an RTX 4090. Buy from a seller with returns and stress-test the memory on arrival.
Are Macs good for running local LLMs?
Apple Silicon is excellent for quiet, always-on setups: unified memory lets a Mac mini M4 Pro or MacBook Pro M4 Max load models a same-price GPU can't fit. Token speed is lower than a discrete NVIDIA card, and the M4 Max now tops out at 96GB unified memory — enough for 70B Q4, not the largest MoE models.
