The brand new Intel 13th-Gen CPUs are finally here, and in a nutshell, they’re very impressive. We’ve got three of the new SKUs into the doors of the Geekawhat offices and we’ve been hard at work testing them out to see how they perform. In today’s gaming PC build we’re making use of the top-end CPU in the new range, the Core i9 13900K. This CPU has more cores and threads than its predecessor on the Alder Lake platform, and unsurprisingly the performance is incredible.
In this build we’ve paired up the Intel Core i9 13900K with Nvidia‘s most powerful GPU, the Founders Edition RTX 4090, and one of Samsung‘s brand new SSDs on the Gen4 interface, the 990 Pro. All of these component make up the most powerful build we’ve ever put together, and what must be the most powerful consumer Gaming PC you can build right now. As always, we’ll be breaking down the main components with some peripherals recommendations towards the end, and of course benchmarks so you can see this PC fly in 4K gaming.

The Intel Core i9 13900K is the most powerful gaming CPU on the market. This is an incredible chip for gaming at 4K and beyond.
CPU: Intel Core i9 13900K
First off is our CPU choice, which as you’ve probably guessed by reading the title, is the Intel Core i9 13900K. This CPU sits on the reworked Alder Lake architecture known as Raptor Lake, bringing an increased core count, better efficiency and higher clock speeds. There were worries that the 13900K wouldn’t offer much of a generational boost compared to the king of performance the 12900K, but Intel have pulled it out of the bag here!
The Core i9 13900K sits at the top of all of our benchmarks in both single and multithreaded performance making it an all-rounder in 4K games, and for a variety of workstation applications. For more detail you can check out our coverage of the new 13th-Gen CPUs on our website, or the full review of the Core i9 13900K.

CPU Cooler: NZXT Kraken X73
The new Intel CPUs have improved efficiency, but the increased TDP means that these new processors do run slightly hotter than we’ve been used to. For this reason, we’ve picked out an excellent CPU cooler that we know will ensure our thermals remain consistent even when the 13900K is under heavy load. NZXT‘s Kraken X73 features a 360mm AIO cooler with an awesome looking infinity mirror, adding great performance and even better visuals in to this build!
