Budget Computer Builds: Maximum Performance Under $800

Introduction

Building a powerful computer on a tight budget doesn't mean sacrificing performance. With careful component selection and smart shopping, you can create a system that handles everyday tasks, light gaming, and productivity work without breaking the bank. This guide will show you how to maximize performance while staying under $800.

Budget Building Philosophy

The 80/20 Rule

Focus 80% of your budget on components that matter most for performance:

• CPU: 25-30% of budget
• RAM: 15-20% of budget
• Storage: 15-20% of budget
• Motherboard: 10-15% of budget
• Power Supply: 10-12% of budget
• Case: 5-8% of budget

Where to Save Money

• Case: Basic but functional cases work fine
• Optical Drive: Skip it - most software is downloaded now
• Fancy Cooling: Stock CPU coolers are adequate for budget builds
• RGB Lighting: Pretty but doesn't improve performance
• Premium Brands: Focus on specifications, not brand prestige

Where NOT to Save Money

• Power Supply: Cheap PSUs can damage components
• Storage: Get an SSD - it's the biggest performance upgrade
• RAM: 8GB minimum, 16GB preferred
• Motherboard: Ensure it has features you need
