High refresh rate monitors cannot be supported by all graphics cards available on the market. You need to be careful while selecting the best GPU for games running in 4K at 120Hz, as trying to match FPS can be quite demanding when in this resolution. Thus, we’ve compiled a list of the top GPUs for the job, along with an explanation of why you should buy each one.
Really, the ultimate GPU for playing any game in 4K is the RTX 4090, a GPU we have extensively reviewed and found there is no better when playing in this resolution. We understand not everyone can afford the best in the world, so have included some more affordable options that are also viable.

Best GPU for 4K 120Hz: RTX 4090
The RTX 4090 is the newer leader in performance. It is the card that will offer unhindered performance to reach the top range of framerates. Especially when it comes to 4K and high resolutions as they require much more VRAM and speed to work better with all the textures.
This also comes at a cost though, as one of the more expensive cards to pick from with an MSRP of $1500 USD, it isn’t exactly a cheap choice. But you can be sure to have it for a while.

Now on the more budget-friendly option, AMD Radeon has your back. The RX 7900 XTX comes in at a cheaper range but with performance not too far behind.
Which also means it has a better value for money. Although if you’re keen on ray tracing, Nvidia still leads in what its architecture can do in that.
