Tips for Choosing the Right CPU-GPU Pair

• Check your resolution goals:
  • 1080p: Mid-range CPUs are enough
  • 1440p: Balance is critical
  • 4K: GPU-heavy workloads, so CPU must keep up
• Consider your refresh rate:
  • 60Hz? Don’t overspend.
  • 144Hz+? Go for balanced high-FPS combos.
• Avoid overkill:
  • A $700 GPU with a $120 CPU will bottleneck.
  • Try to keep the price ratio ~1:1.3 (CPU:GPU).
• Use a bottleneck calculator:
  Always check combinations on a trusted bottleneck calculator to confirm your match.
