LLM on Home Gaming PC
Find your GPU. Copy one command. Get a working local LLM in 10 minutes.
10-Minute Quick Start
-
Install Ollama (Windows / macOS / Linux):
ollama.com/download
-
Pick a model from the table below based on your VRAM.
-
Run it in a terminal, e.g.
ollama run qwen3:14b
-
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.
- 7B Q4 → ~5 GB VRAM
- 14B Q4 → ~9 GB VRAM
- 32B Q4 → ~20 GB VRAM
- 70B Q4 → ~42 GB VRAM (needs dual GPU or Q2/Q3)
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
-
Do not use bf16/fp16 weights on consumer GPUs —
you will waste VRAM. Stick to GGUF Q4/Q5.
-
Context length costs VRAM. 32k context can double
the memory of a small model. Start at 8k.
-
Windows shares VRAM with the desktop. Close Chrome
and games before loading big models, or lose 1-2 GB usable VRAM.
-
Laptop RTX ≠ desktop RTX. An RTX 4070 laptop has
8 GB; the desktop card has 12 GB. Check your actual VRAM with
nvidia-smi.
-
CPU-only is possible but slow. Qwen3 4B on CPU
gets ~5-8 tok/s. Fine for background jobs, painful for chat.
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).
