The CPU sets your frame-rate ceiling. For high-refresh (144Hz+) or 1080p competitive play, lean toward the sweet-spot or high-end pick; at 4K the GPU does most of the work and a budget-tier CPU is usually enough.

Frequently Asked Questions
What CPU do I need for Split Brain?
A Intel Core i3-6100-class processor meets the recommended bar. For high frame rates a AMD FX-6300 gives more headroom. For 1440p+ gaming while streaming, a AMD Ryzen 3 1200 or better is ideal. Verify any chip with our free Can I Run It checker.
Does the CPU matter for Split Brain, or just the GPU?
Gaming is GPU-bound, so the graphics card matters most for raw settings and resolution. But the CPU sets your frame-rate ceiling — it matters most at high refresh rates, at 1080p, and in CPU-heavy games (strategy, simulation, open-world). A weak CPU paired with a strong GPU causes a bottleneck.
Will my CPU bottleneck Split Brain?
It can, if your CPU is much weaker than your GPU. Check the exact balance of your build with our free bottleneck calculator before buying either component.
