A high-end recent release like the Nvidia RTX 3080 delivers extremely smooth 4K gameplay in the latest titles. But mid-range cards like the RTX 3060 Ti also offer compelling value for 1080p gaming. Select a GPU that pairs well with the rest of your system.

Upgrading to a more powerful PSU is often required to provide sufficient power delivery to high-end GPUs. Don't compromise on your power supply.

Central Processing Unit (CPU)

The CPU is the brain of your gaming rig, responsible for essential background tasks like physics calculations, AI logic, game event scripting and handling user input. A faster CPU results in smoother overall gameplay.

For CPU-intensive games, upgrading to a modern processor can help eliminate stuttering and choppiness, especially in crowded multiplayer matches or packed open world environments. Higher single thread performance is ideal for gaming.

Some key considerations for a gaming CPU upgrade:

  • Socket type – Choose a CPU that is compatible with your motherboard socket and chipset.

  • Cores/threads – More cores/threads help with multitasking but games prioritize per-core speed. 6-8 faster cores is optimal.

  • Clock speeds – Higher GHz boost clocks translate to smoother gaming performance. Aim for 4GHz or more.

  • Overclocking – Unlocking CPU multipliers can push performance further. Overclockable "K" CPUs paired with Z-series motherboards allow this.

  • Budget – Determine how much you can spend for the level of CPU performance desired.

Capable processors like the Intel Core i5-12600K or AMD Ryzen 5 5600X represent a nice sweet spot, providing excellent 1080p gaming speeds at a reasonable price point.

Don't forget to upgrade your CPU cooler if buying an unlocked processor for overclocking headroom. Quality cooling is a must.

Random Access Memory (RAM)

RAM stores all the data that games need instant access to like character models, environments, textures and more. Insufficient RAM capacity leads to constant disk swapping as the system struggles to run modern games in cramped memory space.

Upgrading RAM alleviates this bottleneck for smoother gaming. Most gaming rigs today should aim for 16GB or 32GB of RAM. Key points for selecting RAM:

  • Capacity – Get at least 16GB RAM to prevent bottlenecks. 32GB provides breathing room.

  • Speed – Faster DDR4-3200 or DDR4-3600 RAM improves performance compared to base DDR4-2133.

  • Channels – Dual channel RAM doubles bandwidth over single channel configurations. Use matched RAM sticks.

  • Timings – Lower CL timings provide a minor speed boost. But focus on capacity and frequency first.

  • Compatibility – Match the RAM type, speed and voltage to your motherboard's supported specs.

With ample RAM capacity, your games have plenty of high-speed memory for the best possible experience.
