# Desktop & Workstation Hardware Guide (Brazil Focus)
# Desktop & Workstation Hardware Guide
A detailed guide focusing on the Brazilian scenario, crossing high-performance AI models with hardware available in the local market (Mercado Livre, OLX, etc.).
A detailed guide crossing high-performance AI models with hardware availability and pricing (prices in BRL).
> **Important Note:** Proprietary models like **Claude Opus 4.5**, **GPT-5.2**, and **Gemini 3 Pro** represent the cutting edge of Cloud AI. For **Local AI**, we focus on efficiently running models that approximate this power using **MoE (Mixture of Experts)** technology, specifically **GLM-4.7**, **DeepSeek**, and **OSS120B-GPT**.

### 2. The Brazilian Scenario
In Brazil, the **RTX 3060 12GB** and **RTX 3090 24GB** are the most critical cards for AI.
* **Why not 4060 Ti 16GB?** It costs almost double a used 3060. For budget setups ("custo-benefício"), the used 3060 12GB at ~R$ 1.200 is unbeatable.
* **Why the 3090?** To run 70B models, you *need* 24GB. The 4090 is faster, but a used 3090 at R$ 4.000 does the same AI job for 1/3 the price.
### 2. Hardware Selection Strategy
The **RTX 3060 12GB** and **RTX 3090 24GB** are critical cards for AI due to their VRAM-to-Price ratio.
