You do not need a PC that renders 1,000 frames per second simply to display an image on a 1,000Hz monitor. To select the monitor’s maximum refresh mode, you do need the right connection, graphics card, operating system and driver for that specific model. To take advantage of the refresh rate in a game, your CPU, GPU, memory, game and settings must also produce a very high frame rate—and no cited manufacturer establishes a universal CPU or RAM specification that guarantees 1,000 FPS.
Two different requirements: running the display and running a game at 1,000 FPS
A refresh rate describes how often a display can refresh its image. A game’s frame rate describes how many frames the PC renders. The monitor can operate in a 1,000Hz mode while a game produces fewer than 1,000 frames per second; the PC simply will not provide a new, unique game frame for every refresh.
That distinction matters when planning an upgrade. Monitor compatibility is a matter of meeting the model’s connection and system requirements. Matching 1,000Hz with 1,000 rendered frames per second is a much higher and game-dependent performance target, not a prerequisite for seeing an image.
What hardware does the LG 25G590B require for its 1,000Hz mode?
LG’s 2026 U.S. announcement for the UltraGear 25G590B specifies Windows 11, a DisplayPort 2.1 connection, and an NVIDIA RTX 50 series or AMD Radeon RX 9070, 9060 or 7900 series GPU, or newer, for refresh rates up to 1,000Hz. Those are LG’s requirements for this monitor, not a universal recipe for every 1,000Hz display. LG’s product announcement

LG says the 25G590B reaches 1,000Hz at its native Full HD resolution of 1920×1080; it does not require switching to a lower resolution for that mode. LG also advertises an overclocked mode up to 1,100Hz. Its announcement warns that actual performance depends on PC specifications—including CPU, GPU and memory—as well as game-specific frame-rate limits, operating-system version and graphics-driver version. LG says the 1,100Hz overclocked mode may limit Adaptive-Sync support. LG’s product announcement LG’s CES 2026 announcement
Check the resolution and mode behind the 1,000Hz label
A headline refresh rate does not tell you what resolution the monitor uses at that speed or whether it switches modes to reach it. These manufacturer specifications illustrate why those details belong in any comparison:

The LG and Acer figures are manufacturer specifications, not a common independent benchmark comparing gaming performance. Before choosing a display, compare the resolution it retains at maximum refresh, whether the fastest mode is native or uses DFR, the required input and GPU output, and any operating-system, driver or adaptive-sync conditions.
Will your PC run a 1,000Hz monitor?
Start with the monitor’s own specifications rather than assuming that any PC with a modern graphics card can select its top mode. Then consider what you expect to get from it in your games:

- Identify the exact monitor and mode. Check its maximum refresh rate at the resolution you intend to use, and note whether reaching that rate requires DFR or overclocking.
- Verify the connection path. Match the monitor’s required input to an output supported by your GPU. For the LG 25G590B’s up-to-1,000Hz mode, LG specifies DisplayPort 2.1 and the GPU families listed above.
- Check the software requirements. Confirm the required operating-system version and graphics-driver support for the model and mode. For the LG 25G590B, LG specifies Windows 11.
- Check your target game’s frame-rate behavior. CPU and GPU performance, memory, game settings and any game-imposed frame-rate limit can affect how many frames the PC renders. A monitor specification alone cannot establish your game’s sustained frame rate.
- Decide whether the mode trade-offs suit you. A lower resolution at the highest refresh rate or reduced Adaptive-Sync support may matter more than the largest number on the box.
There is no proven universal 1,000-FPS CPU or RAM build
LG names CPU, GPU and memory among the factors that can affect actual performance, but its announcement does not establish a universal processor or memory configuration that sustains 1,000 FPS across games. The cited manufacturer specifications also do not provide a reproducible, independently published benchmark set for sustained 1,000 FPS.
For that reason, it would be misleading to treat a specific CPU or RAM capacity as a guaranteed minimum. Frame rates vary with the game, scene, settings and the rest of the system. Check performance evidence for the specific game and configuration you care about before buying components solely to chase 1,000 FPS.
