What do I need to start gaming on a PC?

If you’re new to PCs, a reputable prebuilt can be a good starting point, especially if individual component prices are high. Compare the exact CPU, graphics card, RAM, storage, power supply, and warranty instead of trusting labels like “gaming PC.” Building it yourself can save money and gives you more control, but buying used is also reasonable if you can test the system and verify the parts.

The main parts you need are a CPU, motherboard, RAM, graphics card, storage drive, power supply, and case. You’ll also need a CPU cooler unless the processor includes one, plus a monitor and basic peripherals. For a general gaming machine, prioritize the graphics card, get at least 16GB of RAM—32GB is more comfortable—and use an SSD rather than a hard drive for your main games and operating system.

Start by setting a maximum budget and deciding whether it includes the monitor, keyboard, mouse, headset, and operating system. Your target resolution and refresh rate matter too—1080p is cheaper, while 1440p at 120Hz or higher needs a stronger graphics card. Once those are clear, your games will tell you what level of hardware to target.

Don’t choose parts before deciding what performance you want. Look at the recommended requirements for the games you play, then build around the most demanding one. A sensible first target would be 1440p gaming with a midrange or better graphics card, but 1080p is perfectly fine and much more affordable. You can also buy the complete system first and upgrade storage, RAM, or the graphics card later.
