What Can I Run AI?

AI PC Builder

Pick a GPU or a complete system, then the rest of the parts. We check compatibility and power, and estimate which models run and how fast.

Quick start

Prices are dated snapshots: GPUs at list price (MSRP) unless marked used; CPUs, boards and SSDs from Newegg and PSUs, cases and RAM from Corsair on 2026-10-23 (new CPU platforms and RM650e priced 2026-11-05). We may earn a commission when you buy through these links, at no extra cost to you.

Memory = weights + 15% + 1 GB at about 4k context; longer context adds the KV cache from each model's config (FP16). Speed = bandwidth ÷ weight size × an efficiency band calibrated on llama.cpp scoreboards; mixture-of-experts models get only an upper bound ("up to"). Multi-GPU adds memory, but speed is about one card's. How we calculate.

New models, and what they need to run

One short email a week: fresh open models with their VRAM numbers, plus hardware worth watching.
