For most 1440p 240Hz gaming PCs, start with the Radeon RX 9070 XT or GeForce RTX 5070 Ti. The RX 9070 XT is the value-oriented choice when its lower street price holds, while the RTX 5070 Ti costs more but adds stronger ray tracing and Nvidia’s DLSS 4.5 and Multi Frame Generation features. Choose the GeForce RTX 5080 only when maximum performance matters more than price: Tom’s Hardware’s October 2026 guide measured it 8%–16% faster than the RTX 5070 Ti, while its September 2026 midpoint price was 51% higher.
A 240Hz monitor sets a refresh ceiling; it does not guarantee 240 frames per second. Your game, graphics preset, ray tracing, upscaling, frame generation, CPU and partner-card settings determine actual frame rates. The recommendations below separate suite averages from the much more important question of whether your own games can sustain high 1% lows.
What you need from a 1440p 240Hz graphics card
Rendering 2560×1440 at 240Hz means the display can show a new frame every 4.17 milliseconds. That is demanding in modern single-player games, especially with ray-traced lighting, but comparatively attainable in competitive titles using sensible settings. No current GPU renders every game at native 1440p, maximum settings and 240fps. Treat 240Hz as the monitor’s capability, then choose a card that can approach your target in the games you actually play.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Separate three targets before buying:
- Native 240fps: Every frame is rendered at 2560×1440 without upscaling or generated intermediates. This is the strictest target.
- Upscaled high refresh: DLSS or FSR renders internally below 1440p and reconstructs the image. A well-supported mode can make 200–240 displayed fps practical with less GPU load.
- High refresh with frame generation: Multi-frame or single-frame generation inserts additional displayed frames. It can raise the counter substantially, but input latency and visual artifacts mean the underlying rendered frame rate still matters.
Use average frame rate and 1% low frame rate separately. An average near 240fps can still feel uneven if 1% lows fall sharply during effects, traversal or multiplayer fights.

Quick recommendations
| GPU | Best for | Evidence and position | Main limitation |
|---|---|---|---|
| Radeon RX 9070 XT | Best value-oriented high-end 1440p choice | Tom’s Hardware describes it as much cheaper than the RTX 5070 Ti in its 2026 snapshot; Tom’s Guide calls it a gaming-value option. AMD lists 16GB GDDR6 and FSR 4 support. | Nvidia leads in some ray-tracing and software-feature comparisons; value changes with local prices and game mix. |
| GeForce RTX 5070 Ti | Feature-rich high-end 1440p | Tom’s Hardware’s high-end recommendation, with DLSS 4.5, Multi Frame Generation and stronger ray tracing than the RX 9070 XT in its stated 2026 suite. | Tom’s Hardware reports up to 53% more cash for about 5% more baseline performance than the RX 9070 XT in its comparison context. |
| GeForce RTX 5080 | Maximum performance without moving to an extreme flagship tier | Reported 8%–16% faster than the RTX 5070 Ti, depending on resolution, in Tom’s Hardware’s October 2026 guide. | September 2026 midpoint price was 51% higher than the RTX 5070 Ti; value is poor unless you prioritize speed. |
| Radeon RX 9070 | Lower-cost 1440p build | AMD includes it among its 1440p options and identifies up to 16GB memory for the RX 9070 series. | A 1440p label is not evidence of 240fps performance; verify game-specific results. |
| Radeon RX 9060 XT 16GB | Budget-conscious 1440p with extra memory headroom | AMD lists the 16GB model among 1440p choices. | Expect more compromises in demanding games and do not assume 240Hz suitability. |
| Arc B580 | Value 1080p/1440p gaming | Tom’s Guide reports above-60fps 1440p maximum-settings performance in its tested context. | That evidence supports value, not a general 240Hz recommendation. |
Radeon RX 9070 XT: the value-first 240Hz candidate
The RX 9070 XT is the sensible starting point when your priority is high 1440p performance without paying a large premium for features you may not use. AMD’s guidance places the RX 9070 series among its 1440p options, with up to 16GB of GDDR6 and support for FSR 4. The 16GB capacity gives modern texture packs more room than lower-memory cards, although capacity alone does not determine frame rate.
Tom’s Hardware’s 2026 comparison says the RTX 5070 Ti can cost as much as 53% more for roughly 5% more baseline performance than the RX 9070 XT in its stated snapshot. Those are not permanent prices or a universal benchmark result; they describe that guide’s tested cards and market snapshot. Check current local pricing before deciding that either card is the better buy.
Choose it when
- Your games are mostly rasterized esports, action or role-playing titles where ray tracing is optional.
- You want 16GB of memory and are comfortable using FSR when a demanding title cannot reach your refresh target natively.
- The RX 9070 XT is materially cheaper than a comparable RTX 5070 Ti in your region.
Look elsewhere when
- Ray-traced effects are central to your preferred games and you want the strongest performance in that mode.
- You specifically want DLSS 4.5 or Multi Frame Generation and those features are supported in your game list.
GeForce RTX 5070 Ti: pay for ray tracing and software features
The RTX 5070 Ti is the feature-led alternative. Tom’s Hardware recommends it as a high-end 1440p card and reports stronger ray tracing than the RX 9070 XT in its 2026 test suite. Its cited feature set includes DLSS 4.5 and Multi Frame Generation, which can raise displayed frame rates in supported games when the base rendered frame rate is already healthy.
Recommended Free Tools
The trade-off is price efficiency. In Tom’s Hardware’s comparison context, the RTX 5070 Ti may require up to 53% more cash for about 5% more baseline performance than the RX 9070 XT. That gap can be justified by ray-tracing quality, game support or creator-workflow requirements, but it is difficult to justify solely for a higher average in conventional rasterized games.
Choose it when
- You regularly enable ray tracing and want the better result shown in Nvidia-focused comparisons.
- Your game library includes DLSS-supported titles and you value reconstruction or frame-generation options.
- Local pricing is close enough that the feature premium fits your budget.
Check before buying
- Confirm that the exact games you play support the DLSS mode and frame-generation feature you expect.
- Decide whether generated frames count toward your personal 240Hz goal; they increase displayed motion samples but are not equivalent to native rendered frames.
GeForce RTX 5080: a costly step up
The RTX 5080 is for readers who would rather buy additional performance than optimize price per frame. Tom’s Hardware reports an 8%–16% speed advantage over the RTX 5070 Ti, with the percentage changing by resolution in its October 2026 guide. That is a meaningful but not transformative increase for a 240Hz target: a game running at 180fps will not automatically become a locked 240fps title.
The price premium is much larger. Tom’s Hardware’s September 2026 snapshot put the RTX 5080’s midpoint price 51% above the RTX 5070 Ti. Because prices and stock move, use that percentage as a dated value warning rather than a current quote. Buy it when you have already selected a high-refresh monitor, a fast CPU and demanding games where the extra frames are useful.
Lower-cost cards and realistic expectations
Radeon RX 9070
AMD identifies the RX 9070 as a 1440p option. It can make sense for a lower-cost build, particularly when your monitor is 144Hz most of the time and 240Hz is a competitive-game mode. Do not turn AMD’s 1440p suitability label into a promise of 240fps. Check independent results for each game, preset and upscaling mode.

The 16GB RX 9060 XT is another AMD-listed 1440p choice. Its memory capacity is useful for texture-heavy games, but the GPU tier means you should expect to reduce settings or use upscaling sooner than with the RX 9070 XT. It is a sensible budget option only if your target is flexible.
Arc B580
Tom’s Guide lists the Arc B580 as a budget card with strong 1080p and 1440p performance and reports more than 60fps at 1440p maximum settings in its tested context. That is useful value evidence, not 240Hz evidence. Choose it for affordable 1440p play, not as the default card for a 240Hz competitive monitor.
What the published benchmarks actually show
TechSpot’s 2026 52-game comparison measured the RX 9070 XT at a 24% higher average frame rate than the GeForce RTX 5070 at 1440p. It also calculated a 37% cost-per-frame premium for the RTX 5070 using the prices and results tested in that review. This is not a direct RTX 5070 Ti comparison, so do not substitute the RTX 5070’s percentage for the high-end buying decision.
Tom’s Hardware and TechSpot use different game suites, settings and price snapshots. Their percentages cannot be combined into one controlled ranking. Use them to understand direction: the RX 9070 XT can be very competitive in rasterized 1440p value, while the RTX 5070 Ti and RTX 5080 target buyers who value Nvidia features, ray tracing or additional speed.

AMD’s own 1440p material comes from internal laboratory testing. Manufacturer numbers are useful for identifying supported features and product positioning, but balance them with independent tests in the games you play.
Choose by game type and rendering mode
Competitive shooters and esports
These games often reach very high frame rates with reduced effects. Prioritize consistent 1% lows, CPU performance and low-latency settings over ray tracing. An RX 9070 XT or RTX 5070 Ti gives ample headroom for a 240Hz display in many titles, but verify the exact game rather than assuming a universal result.
Ray-traced single-player games
Enable ray tracing in a benchmark or short repeatable scene, then compare native and upscaled modes. The RTX 5070 Ti is the safer feature choice according to Tom’s Hardware’s 2026 suite. If the RTX 5080’s extra 8%–16% performance keeps your chosen title above its desired 1% low, its premium may be worthwhile.
Rasterized open-world and simulation games
These can be limited by the CPU or by heavy world streaming before the GPU reaches full utilization. The RX 9070 XT’s value advantage is most compelling when ray tracing is disabled and local pricing is favorable. Monitor both GPU utilization and frame-time consistency.

Board-partner versions of the same GPU differ in length, thickness, power connectors, cooler design and factory settings. Before ordering, open the exact product listing and compare it with your case, motherboard and power supply documentation.
- Case clearance: Measure available card length and height, including front fans, radiator space and side-panel clearance.
- Slot thickness: Confirm that neighboring expansion slots remain usable and that the card does not collide with a vertical mount or capture card.
- Power supply: Check the manufacturer’s recommended wattage and the connectors on the specific board-partner model. Use dedicated cables where the documentation calls for them.
- Display connection: Verify that the card and monitor share an input capable of 2560×1440 at 240Hz, then select the correct refresh rate in the operating system and monitor menu.
- CPU balance: A fast GPU cannot produce 240fps when the processor, game engine or simulation thread is the bottleneck.
- Memory and storage: Adequate system memory and a responsive game drive reduce streaming-related hitching, but they do not replace GPU performance.
How to configure a 240Hz setup
- Install the card in the primary full-bandwidth PCIe slot and connect every required power lead listed for the exact model.
- Connect the monitor with the recommended high-bandwidth input, then open the operating-system display settings and choose 2560×1440 at 240Hz.
- Update the graphics driver and restart before benchmarking. Record the driver version with your results.
- Start with a native 1440p preset and ray tracing disabled. Measure average fps and 1% lows in a repeatable game scene.
- Raise or lower individual settings that affect frame time most, such as shadows, volumetrics, reflections and crowd density. Keep a written record so comparisons remain meaningful.
- If native performance is below target, enable the game’s supported DLSS or FSR mode and retest. Label the result as upscaled.
- Use frame generation only after the underlying rendered frame rate is stable and input latency remains acceptable. Record generated and non-generated results separately.
- Cap the frame rate only if a cap improves frame-time consistency, acoustics or power use. A cap is not a substitute for enough GPU or CPU headroom.
Common problems and fixes
The game never reaches 240fps
Check whether the limit is the GPU, CPU, an in-game cap or a background process. Lower the heaviest settings one at a time and compare 1% lows. If GPU utilization is low while one CPU thread is saturated, a faster graphics card may not help.
The monitor is stuck at 60Hz or 144Hz
Recheck the cable, input selection and both the operating-system refresh menu and the monitor’s on-screen display. Some monitors expose 240Hz only after a specific input mode is enabled.
Frame generation feels laggy
Generated frames cannot fix a low underlying render rate. Disable the feature, stabilize the base fps and latency, then test it again. Compare motion and controls in the same scene rather than relying only on the displayed counter.
Stutter appears despite a high average
Watch 1% lows and frame-time graphs. Shader compilation, asset streaming, CPU limits, background recording and thermal throttling can all create spikes. Reduce the setting that causes the spikes, close unnecessary overlays and confirm that temperatures and clocks remain stable.
Decision guide
| Your priority | Most defensible choice | Reason |
|---|---|---|
| Best high-end value at current prices | Radeon RX 9070 XT | Strong 1440p positioning, 16GB GDDR6 and a potentially much lower price than RTX 5070 Ti. |
| Ray tracing and DLSS features | GeForce RTX 5070 Ti | Stronger ray tracing in Tom’s Hardware’s suite plus DLSS 4.5 and Multi Frame Generation. |
| Highest performance among these options | GeForce RTX 5080 | 8%–16% faster than RTX 5070 Ti in the cited guide, at a substantially higher price. |
| Lower-budget 1440p | Radeon RX 9070, RX 9060 XT 16GB or Arc B580 | Appropriate for value-focused 1440p builds; none should be treated as a guaranteed 240fps card. |
For a new 240Hz build, compare the RX 9070 XT and RTX 5070 Ti at the prices of the exact cards available to you. Pick the RX 9070 XT when value and rasterized performance dominate; pay for the RTX 5070 Ti when ray tracing, DLSS support or frame-generation behavior is central to your games. Move to the RTX 5080 only when the measured 8%–16% uplift solves a specific performance need that the cheaper cards cannot.
