While some DIY gaming PC enthusiasts will insist that a graphics card is the most important component of a build, that would actually be your CPU. The CPU is the brain of your computer, and without it, you're stuck with a very expensive box on your desk.
Having the right CPU for your gaming PC is important to make everything run efficiently. You need to make sure you aren't mixing Intel and AMD components as well as incompatible generations -- new AMD 7000 series processors use an AM5 socket rather than the AM4 of the previous 5000 series.
To help you find the right gaming CPU for your build, I've put together a list of the very best you can buy. I've also broken down their top features like base and boosted clock speeds as well as core counts to help you find the best fit for your budget and build.

Shopping for a gaming CPU can be overwhelming if you're unfamiliar with CPU lingo. CPUs have their own language, which can be confusing to the novice user.
When searching for a new CPU for gaming, these are some considerations that can help you find the right CPU model for your needs.
Another great way to find the best CPU for gaming in 2023 is to look at the PC games you intend to play. The specifications can help you buy the right CPU for your personal needs.
CPU stands for "central processing unit." You can think of the CPU as the brain of your computer. It provides the basic structure and power the rest of your components need to carry out tasks and run programs.
That depends on what issues you're having. If games are running a bit slow or having trouble launching, it's time to upgrade your graphics card since that is what controls loading in-game assets. However, if your entire PC is running slow or having trouble performing basic tasks, it's probably best to get a new CPU.
The difference between AMD and Intel components is similar to the difference between Windows and Mac-based computers. Both use proprietary programming languages and architecture to achieve desired results. And as such, they do NOT work together, which means that you can't buy a cheap Intel motherboard and AMD CPU and expect them to run your PC. Not only would the AMD CPU simply not fit into the motherboard, it also doesn't have the necessary programming to communicate with Intel components.
To make sure your new gaming CPU is going to work with your build, you can check out , a website designed to help you create a fully compatible build with a budget for new components. You simply select what components you want to buy, and the website checks to make sure everything is compatible. And if there are any problems, it flags the issue so you know exactly what you need to change to make everything work together.
A normal operating range for a CPU while you're playing games is 142-164 F (61-73 C). Your CPU may run a bit hotter at times, depending on graphical load and ambient temperature, but that shouldn't cause any damage.
If your CPU is running at a much hotter temperature, you may need to invest in a better cooling fan, some thermal paste to help draw excess heat to the dissipation fins, or even a liquid cooling system. There are all kinds of programs out there to help you monitor your CPU temperature, and I highly recommend using one so you can catch issues before they ruin your gaming rig.
In our search for the best gaming CPUs, we came across several options that may be worth your consideration. These are some of the other CPUs we considered for 2023's best CPUs for gaming:
