LLM on Home Gaming PC

Find your GPU. Copy one command. Get a working local LLM in 10 minutes.

10-Minute Quick Start

  1. Install Ollama (Windows / macOS / Linux): ollama.com/download
  2. Pick a model from the table below based on your VRAM.
  3. Run it in a terminal, e.g. ollama run qwen3:14b
  4. Want a GUI? Install LM Studio or Open WebUI.

Pick by GPU (2026)

Numbers assume Q4_K_M quantization via Ollama / llama.cpp, 8k context, Windows 11 or Linux with recent NVIDIA drivers. Tokens/sec are real-world decode speeds, not theoretical peaks.

What to Run for Each Job

Coding assistant

12 GB: ollama run qwen2.5-coder:14b

16 GB: ollama run qwen2.5-coder:14b-instruct-q5_K_M

24 GB: ollama run qwen2.5-coder:32b

Qwen2.5-Coder is the strongest open coder in its size class. Pair with Continue.dev in VS Code for a Copilot-style setup.

Reasoning & math

8 GB: ollama run deepseek-r1:8b

16 GB: ollama run deepseek-r1:14b

24 GB: ollama run deepseek-r1:32b

DeepSeek R1 distills show visible chain-of-thought. Great for step-by-step problems; slower than plain instruct models.

General chat & writing

8 GB: ollama run qwen3:8b

12 GB: ollama run gemma4:12b

24 GB: ollama run gemma4:31b

Gemma 4 is Apache-2.0-friendly and neutral in tone. Qwen3 8B is the strongest all-rounder at 8 GB.

Vision (image + text)

12 GB: ollama run gemma4:12b

24 GB: ollama run qwen3.8:27b

Good for OCR, screenshot Q&A, and describing local photos entirely offline.

Nordic / multilingual

12 GB: ollama run qwen3:8b

24 GB: ollama run gemma4:31b

Qwen3.8 and Gemma 4 handle Norwegian, Swedish, and Danish acceptably. Verify on your own prompts — small models still stumble on idioms.

Uncensored / roleplay

12 GB: ollama run dolphin-mixtral:8x7b

24 GB: ollama run nous-hermes2:34b

Community fine-tunes with fewer refusals. Use responsibly — you still own the output.

VRAM Rule of Thumb

To estimate VRAM needed for a model at Q4: parameters × 0.6 GB. Add ~1-2 GB for context (8k) and overhead.

If it does not fit, drop to Q3 (small quality loss) or Q2 (noticeable quality loss) before dropping a model tier.

Buying a New Rig? Two Recipes.

Budget builder (~$1,500)

  • GPU: RTX 5070 12 GB
  • CPU: Ryzen 7 7700
  • RAM: 32 GB DDR5-6000
  • SSD: 1 TB NVMe Gen4

Runs Qwen3 14B at ~55 tok/s. Plays every 2026 game at 1440p high.

Serious local LLM (~$3,500)

  • GPU: RTX 5090 32 GB
  • CPU: Ryzen 9 7950X3D
  • RAM: 64 GB DDR5-6000
  • SSD: 2 TB NVMe Gen4

Runs Qwen3.8 27B comfortably at Q5. Room for 256k context on smaller models.

Common Traps

Quick Buying Rule

Gaming + casual LLM: aim for 12 GB VRAM (RTX 5070 or 4070 Super). Serious local coding/reasoning: aim for 24-32 GB VRAM (RTX 4090 or 5090).
