5 best GPUs for the Intel Core i9 13900K chip

The 13th gen Raptor Lake-based Core i9 13900K is the latest 24-core flagship processor from Team Blue. The chip is a slight step up from the last-gen Core i9 12900K and is arguably one of the fastest gaming CPUs on the market.

Although it has been ousted by Intel's 13900KS and, lately, AMD's Ryzen 9 7950X3D, the 13900K continues to be one of the more practical options perfect for high-end gaming.

However, gamers should invest in a capable graphics card to utilize the power of the Raptor Lake flagship. It is also worth noting that the Core i9 is built for professionals and creators. Therefore, gamers won't likely be using the full potential the 13900K can offer.
