Best GPU for 1440p 240Hz (2026)

What 240Hz at 1440p really means

1440p 240Hz is two different targets in one monitor. In competitive games like Valorant, CS2, Overwatch 2, Fortnite and Apex Legends, 240 fps at 1440p is very doable on a midrange to upper-midrange card. In single-player AAA games like Cyberpunk 2077, Alan Wake 2, Black Myth: Wukong and Starfield with ultra settings and ray tracing, no current GPU holds 240 fps at 1440p. Most top cards land at 100 to 160 fps there, even with DLSS or FSR.

Buy for the games you actually play. If you live in esports titles and want every Hz, you can spend less and put the savings toward a fast CPU and low-latency RAM, because at 300+ fps you are usually CPU-limited. If you want AAA games to feel close to 240Hz, you need to budget for the tier above and be willing to use upscaling and tuned settings. There is no setting that makes a $350 card do both.

Quick comparison

This assumes a modern CPU like a Ryzen 7 7800X3D or i7-14700K, 1440p, and upscaling set to Quality where noted. Numbers are typical averages from my testing mix, not a single benchmark run.

Best overall: RTX 4070 Super and RTX 4070 Ti Super class

For most 1440p 240Hz buyers, this is the sweet spot. An RTX 4070 Super easily clears 240 fps in Valorant, CS2 and Overwatch 2 at 1440p, and usually holds 200+ in Fortnite with Performance mode or tuned Epic settings. In Warzone and Apex it sits around 160-200 fps at competitive settings, which still feels excellent on a 240Hz monitor with G-Sync on. Check current RTX 4070 Super prices if you mainly play shooters, because street prices move a lot.

The step up to an RTX 4070 Ti Super matters if you also play AAA games. That extra VRAM and bandwidth – 16GB versus 12GB – shows up at 1440p ultra with high-res textures, especially in modded games or titles like Hogwarts Legacy, The Last of Us Part I and Starfield. You also get stronger DLSS 3 Frame Generation performance, which is the only realistic way to push AAA games from 120 fps toward 170-200 fps.

Trade-offs: 12GB on the base 4070 Super is fine for esports but is already tight for maxed AAA with ray tracing. You will need to drop texture pools or enable DLSS. Failure mode I see often is buyers pairing these cards with an old Ryzen 5 3600 or i7-9700K, then wondering why Valorant will not hit 240 fps stable. At those frame rates, 1% lows are CPU-driven. Update BIOS, enable Resizable BAR, use DisplayPort 1.4, and turn on G-Sync + V-Sync in Nvidia Control Panel with an in-game cap at 237 fps to avoid tearing without adding much latency.

Best AMD value: RX 7800 XT and RX 7900 XT

If you do not care about ray tracing or streaming features, AMD is usually cheaper per frame at 1440p. The RX 7800 XT with 16GB is the honest minimum I would buy for a 240Hz 1440p monitor if you play a mix. It beats or matches the 4070-class in rasterized AAA games and has no problem pushing 240+ in lighter esports titles. Browse RX 7800 XT listings when you want 16GB without paying the Nvidia tax.

The RX 7900 XT with 20GB is the better pick for AAA-first players who want to avoid VRAM anxiety. In my testing it trades blows with the 4070 Ti Super in raster, often winning by 5-10% at 1440p ultra without ray tracing, and the extra VRAM helps with texture-heavy games. It also undervolts well, which cuts noise a lot on reference-style coolers.

Trade-offs: Ray tracing is still a full tier behind Nvidia. In Cyberpunk with full ray tracing or Alan Wake 2 with path tracing, AMD needs heavier FSR upscaling and still falls short. FSR 3 Frame Generation has improved but in my experience still has more ghosting than DLSS 3. AV1 encoding is good now, but if you stream daily, Nvidia NVENC remains cleaner at low bitrates. Failure mode is power spikes – a 7900 XT can spike well above its rated board power, so do not reuse a tired 650W PSU. Use two separate PCIe cables, not a daisy chain.

For pushing AAA toward 240Hz: RTX 4080 Super and RX 7900 XTX

Let me be direct: even these cards do not do native 240 fps in demanding AAA at ultra. What they do is make 140-180 fps feel normal, and 180-220 fps reachable with DLSS Quality + Frame Generation and sensible settings. If you play story games on a 240Hz OLED and want maximum motion clarity without dropping to 1080p, this is the tier that makes sense. Compare RTX 4080 Super models and prices against the 7900 XTX before you decide.

Pick the RTX 4080 Super if you use ray tracing, DLSS, Frame Generation, or Blender, DaVinci Resolve and AI work. It is quieter and far more efficient than the 7900 XTX, typically 300-320W versus 350W+, and DLSS Super Resolution at 1440p Quality looks noticeably better than FSR in motion. Pick the RX 7900 XTX if you want 24GB VRAM and the best raster fps per dollar and you play with ray tracing off. In Starfield, Remnant 2 and raster-heavy Unreal Engine 5 games, it is excellent.

Trade-offs: Both are overkill if you only play Valorant and CS2 – you will be CPU-limited and paying $400 extra for no visible gain. Failure modes are physical: these are 320mm+ triple-slot cards that sag and choke in small cases. Measure your case, use a support bracket, and confirm you have a native 12VHPWR cable or clean adapter routing with no sharp bend within 35mm of the connector on Nvidia cards.

What not to buy for this monitor

Do not buy an 8GB card for 1440p 240Hz in 2026 unless it is strictly a stopgap for esports. The RTX 4060 Ti 8GB and older RX 6600-class cards can hit 240 fps in Valorant, but they stutter in Warzone, Hogwarts Legacy and new UE5 ports when textures overflow VRAM. The cheaper option is only fine if you know you will stay on competitive settings and upgrade the CPU first.

Intel Arc A770 and A750 are interesting budget options with 16GB and 8GB, and drivers are much better than at launch, but frame-time consistency at very high refresh still lags behind AMD and Nvidia in my testing. Fine for 1440p 144Hz on a budget, not what I would pair with a 240Hz panel you paid extra for.

Also check your cable and port. Many 1440p 240Hz monitors need DisplayPort 1.4 with DSC to hit full refresh with 10-bit color. HDMI 2.0 will cap you at 144Hz. Use the cable in the box first, update monitor firmware, then set 240Hz in Windows Advanced Display settings. I have seen a lot of expensive GPUs blamed for a cable limit.

FAQ

How much VRAM do I need for 1440p 240Hz?

12GB is workable for esports and tuned AAA, 16GB is the comfortable spot for ultra textures at 1440p, and 20GB+ only matters if you mod heavily or keep cards for 4-5 years. VRAM does not increase fps by itself, but running out causes harsh stutter.

Do I need Frame Generation to hit 240 fps?

In esports, no – you should leave it off for lowest latency. In AAA single-player games, yes, DLSS 3 or FSR 3 Frame Generation is often the only way to go from 120-140 fps to 180+ fps. Do not use it in competitive shooters.

Will my CPU stop me from reaching 240 fps?

Probably, in esports titles. At 1440p low settings pushing 250+ fps, a Ryzen 7 7800X3D or equivalent makes a bigger difference than moving from a 4070 Super to a 4080 Super. If your 1% lows are under 180 fps while GPU usage is under 70%, you are CPU-limited.

Is G-Sync / FreeSync still worth it at 240Hz?

Yes. You will rarely lock to exactly 240 fps, so adaptive sync prevents tearing when you swing between 160 and 240 fps. Enable G-Sync Compatible or FreeSync, cap fps 3 below max, and turn on Low Latency Mode in esports games.
