Can a 5080/9800X3D setup actually run 480Hz at 1440p?

Technically, you won't see native 480fps in most games, but using heavy DLSS and frame generation could give you some inflated frame counts, albeit with a potential trade-off in input lag. Just keep in mind that for high-stakes competitive play, this might not be the best route.

With some upscaling techniques and DLSS, you might see higher frame rates, especially in games that aren't heavy on ray tracing. For something like COD or Battlefield, you could push over 500fps with the right settings, but again, those are specific cases.

The ability to hit 480fps depends heavily on the game and your settings. While lighter esports titles can get up there, most modern games won't reach that mark even with the best setup. For example, in games like CS:Go you might hit those frames if you lower the settings, but in AAA titles, that’s pretty much impossible.

In general, you probably won't reach 480fps in most games. For example, The Finals at 1440p with DLSS gives around 300fps, but for heavier games like Apex Legends, you’re capped around 300fps due to engine limits. If competitive gaming is your goal, you might consider adjusting your expectations.

While the 9800X3D is a stellar processor, the reality is that unless you’re willing to invest in a 4090 or 5090, the 5080/9800X3D combo is the top tier you're going to achieve for gaming. So, manage your expectations regarding frame rates. Don't count on hitting 480 fps without spending a lot more.
