A 240Hz 2560×1440 monitor is demanding, but the best GPU depends more on the games you play and the settings you expect than on the refresh-rate number alone. Competitive games can reach 240 frames per second on a much cheaper card than a demanding single-player game can. For the latter, even a high-end GPU may need reduced settings, upscaling, or frame generation to approach 240 fps.
For a broad mix of games, look first at the GeForce RTX 5080 class if you want strong performance and access to NVIDIA’s ray-tracing and upscaling features. If you mainly play esports or are willing to tune settings, a lower-priced card can be the smarter buy.
What 240Hz at 1440p really demands
“2K” is commonly used to mean 2560×1440, or 1440p, on gaming monitors. That is about 78% more pixels than 1080p, so maintaining high frame rates takes substantially more GPU power. A 240Hz screen can display up to 240 refreshes per second, but that does not mean every game needs to run at exactly 240 fps to feel responsive.
In esports titles such as Counter-Strike 2, Valorant, or Rocket League, high frame rates are realistic with a suitable GPU and sensible settings. In demanding games with ray tracing enabled, 240 fps is usually an unrealistic target at native resolution. Also check your processor: at very high frame rates, a CPU bottleneck can keep a faster GPU from delivering its full potential.
Best GPU options by type of player
| GPU tier | Best fit | Main trade-off |
|---|---|---|
| High-end NVIDIA | Mixed games, ray tracing, high settings | Costs more; 240 fps in demanding games still isn’t guaranteed |
| Upper-midrange AMD | High raster performance without prioritizing ray tracing | Ray tracing and feature preferences may favor NVIDIA |
| Midrange GPU | Esports, tuned settings, or a tighter budget | Less headroom for new demanding games |
Best for demanding games: high-end NVIDIA
A GeForce RTX 5080-class card is a strong choice if you want one GPU for competitive play and visually demanding games. It offers substantial 1440p performance, plus access to NVIDIA’s ray tracing and DLSS features. Those features can improve the experience in supported games, though upscaling and frame generation are not the same as rendering every frame natively.
The catch is price: paying for a high-end card makes little sense if you mostly play lightweight esports titles, or if your CPU cannot keep up. Nor should you buy it expecting every new game at maximum settings, ray tracing, and 240 fps at once. Check the specific card’s power requirements and your power supply before ordering; an undersized PSU or cramped case can turn a performance upgrade into a compatibility problem.
Best value for raster performance: upper-midrange AMD
If ray tracing is not a priority, an upper-midrange Radeon RX 9070 XT-class card is worth comparing. AMD cards can be compelling for traditional rasterized gaming, where the game is rendered without demanding ray-tracing effects. That makes this tier a good fit for players who want high settings and strong frame rates while keeping spending below the top end.
Its failure mode is buying on average benchmark results alone. Performance varies by game, and heavy ray tracing can change the ranking. Look up tests for the games you actually play, including minimum frame rates if available; dips and stutter matter more than a high average when you are chasing a responsive feel. If ray tracing is central to your games, compare NVIDIA and AMD results in those titles before choosing.
When a midrange card is enough
A midrange 1440p gaming GPU can be the right purchase if you mainly play competitive games, are comfortable lowering shadows or other demanding settings, or do not need 240 fps in every title. It can also leave money for a faster CPU, a better monitor, or a larger SSD—upgrades that may matter more to your setup than buying the fastest card available.
The compromise is reduced headroom. A card that reaches high frame rates in today’s esports games may need lower settings in newer releases, and it may struggle to keep frame rates consistently high in demanding single-player games. If you want to use the monitor for several years without tuning settings, stepping up a tier is safer. If you mostly play one well-optimized competitive game, paying extra for that headroom may bring little practical benefit.
Check these details before you buy
Compare benchmarks at 1440p, not just 4K or 1080p, and look for results from your own games. Decide whether your target is a 240 fps average, consistently high frame rates, or simply making use of the monitor’s refresh rate. Those are different goals. Variable refresh rate can help smooth frame rates below 240 fps, but it does not make a slower GPU deliver 240 fps.
Finally, check card length, thickness, power connectors, and recommended PSU capacity against your PC. A powerful card that blocks another component, does not fit the case, or requires a PSU upgrade can cost more than its advertised price. Leave room in your budget for those practical constraints.
FAQ
Do I need 240 fps to use a 240Hz monitor?
No. The monitor can still run at 240Hz when a game produces fewer frames, and variable refresh rate can help reduce tearing or uneven motion. More frames can improve responsiveness, but they are not an all-or-nothing requirement.
Is an expensive GPU necessary for 1440p 240Hz?
Not for every game. Esports titles are much easier to run at high frame rates than demanding games with ray tracing. Choose based on your actual games and settings, not the monitor’s refresh rate alone.
Should I enable ray tracing?
Only if you value the visual effect enough to accept its performance cost. In demanding games, ray tracing can make 240 fps especially difficult to reach at 1440p.
Will my CPU limit a high-end GPU?
It can, particularly in competitive games at very high frame rates. Check CPU and GPU usage in the games you play; if the processor is holding back performance, replacing the GPU alone may not reach your target.
