When it comes to gaming rigs, CPUs can often be overlooked. Getting the best CPU for PC gaming is vital, even if you're more likely to spend more money on a graphics card. While the GPUs on a graphics card take care of rendering, your CPU handles things like enemy AI in a shooter, and is even more evident in 4X and strategy games in which enemy AI utilise a whole host of systems to make tactical decisions to take you out. Your CPU really is the heart of your build too, making everything run much faster and smoother, so picking up a decent core is absolutely essential.
Your CPU acts as the bridge between all of the other kit stuffed into your gaming case (along with your RAM), so it has quite the heavy load to be carrying. With that in mind we’ve selected a handful of the best CPUs you can get right now at competitive prices to meet all of your needs. If you're building your own rig you already know what the best CPU for PC gaming is... but we check the price of all major online retailers to ensure you're getting the parts cheaper, at any given time. On top of that, we recommend higher and lower spec CPUs, to help you manage the budget for your build. With our help you'll have a machine capable of running the best PC games in no time...

AMD Ryzen 7 2700
The best overall CPU
Cores: 8 | Threads: 16 | Base Clock: 3.2GHz | Overclocking: Yes, 4.3GHz typical | L3 Cache: 16 MB | TDP: 65W | PCIe 3.0 lanes: 20
The Ryzen 7 is an impressive line, eclipsing the dark days around the beginning of this decade when AMD was stuck as a second place CPU manufacturer with its misguided line of industrial-vehicle-named processors (Bulldozer, Steamroller, etc.). Starting with the first Ryzens and their all new x86 Zen core architecture, AMD has been providing power and performance to rival Intel’s best efforts at a fraction of the price.
The 2700X is the highlight of the latest iteration of Ryzen processors, providing a significant increase in power despite launching at a lower price point than its well regarded predecessor, the 1800X. Mighty cache and memory performance are supported by an improved ability to reach 4.0GHZ even when all eight cores are engaged, and a streamlined, better designed processing management engine. The 2700X is a tremendous centerpiece of both a top-notch machine built for demanding work applications as well as a beast for gaming, and our top pick for an impressive CPU that’s remarkably affordable.
AMD Ryzen 3 2200G
Best budget CPU
Cores: 4 | Threads: 4 | Base Clock: 3.5GHz | Overclocking: Yes, 4.0GHz typical | L3 Cache: 4MB | TDP: 65W | PCIe 3.0 lanes: 12
The problem with high end CPUs is that all that additional processing power comes with a correspondingly high price tag, and for a lot of gamers, that additional horsepower is largely wasted, particularly if you aren’t taxing your machine with a heavy workload outside of gaming. While a CPU is important for gaming, if you’re satisfied playing on slightly lower settings, the Ryzen 3 2200G is an incredible value that still provides a solid amount of power.
Another big advantage of the 2200G for gamers on a shoestring budget is that it includes modest integrated graphics capability that can tide you over until you can afford a proper GPU. If you’re trying to build a budget PC that will get you in the gaming door but leave you plenty of cash to actually purchase some of those games you’re craving, the 2200G is an excellent starting point.
Intel Core i7-8700K
For the power gamer
Cores: 6 | Threads: 12 | Base Clock: 3.7GHz | Overclocking: Yes, 4.9-5.0GHz typical | L3 Cache: 12MB | TDP: 95W | PCIe 3.0 lanes: 16
Then there’s the total opposite end of the spectrum, powerful CPUs that are roaring computational beasts and will happily devour every speck of data your software throws its way, a category that starts with processor's like Intel’s 8700K. Intel’s core is specifically tailored for gamers that aren’t as interested in performance in peripheral applications, who just want the rawest potential to run games at the highest end of performance. High clock speed contributes to some of the best framerates of any mid-range contemporary CPU, and while it’s more expensive than AMD’s alternatives, if you’re a gamer with a swollen bank account and value performance, it's a strong option.

Intel Core i9-7980XE
For wealthy future-proofers and early adopters
Cores: 18 | Threads: 36 | Base Clock: 2.6GHz | Overclocking: Yes, 4.1GHz typical | L3 Cache: 24.75MB | TDP: 165W | PCIe 3.0 lanes: 44
If the 8700X is a superhero bristling with raw power, the 7980XE is Thanos. Its insane 18 cores and 36 threads provide a ludicrous level of performance that is, frankly, massive overkill except for the truly obsessed (and very rich). It's a CPU custom made for early adopters who demand the most cutting edge performance on the market. For those with the budget to afford it, however, the 7980XE is an incredible work of technological art, the fastest desktop processor on the market, and getting in now ensures that you won’t need an upgrade for many years to come. It’s tough to imagine even the next generation of games beginning to challenge the 7980’s capabilities until very late in the cycle, if ever, meaning for gamers it’s the last CPU you’ll need to buy for a very, very long time.
AMD Ryzen Threadripper 1950X
For the professional that games as a hobby
Cores: 16 | Threads: 32 | Base Clock: 3.4GHz | Overclocking: Yes, 3.9GHz typical | L3 Cache: 32MB | TDP: 180W | PCIe 3.0 lanes: 64
On the other hand, if you’re in the market for some truly explosive power but aren’t obsessed with having the absolute zenith of CPU tech, AMD’s blistering Threadripper 1950X is a great solution at almost half the price of the 7980XE. While it’s built for desktop applications first, being an adaptation of AMD’s Epyc server CPU, it’s no slouch for gaming and remains amongst the highest performing CPUs on the market. The Threadripper is perfect for the sort of gamer who loves to multitask, pushing a processor by demanding top performance in games while balancing a heavy workload of other programs, be they streaming or browsing or rendering or all of the above. If you’re a gamer who also leans heavily on your PC for work functions, and don’t want to push all the way up to the 7980XE, the Threadripper will fit your needs like a perfectly tailored suit.
