💡 General Bottleneck Avoidance Tips:
- Pair RTX 3070 or higher with at least a 6-core / 12-thread CPU
- Always go dual-channel RAM (16GB minimum for gaming, 32GB for editing)
- Use Gen4 SSD for faster texture & asset loading
- For 4K workloads, prioritize CPU with strong single-core and cache performance
🔍 FAQs
Q: Can I use RTX 4090 with i5 processor?
A: Technically yes, but it will heavily bottleneck performance. Use i7/i9 or Ryzen 9 for balance.
Q: Which CPU is best for RTX 4060 Ti?
A: Intel i5-13400F or Ryzen 5 7600 for budget builds. For long-term performance, i5-13600K is even better.
Q: Will Ryzen 5 5600 bottleneck RTX 3070?
A: Slightly at 1440p or higher. Use Ryzen 7 5800X3D for optimal pairing.
