The RTX 5090 should be enough for Atomic Heart at 1440p with room to spare. This SA gamer's verdict covers ray tracing, CPU balance, high-refresh displays, thermals, and benchmark caution for exact FPS.
Yes. The RTX 5090 (32GB) runs Atomic Heart at 1440p at roughly 240 fps with high settings. Atomic Heart is an Unreal-engine FPS with heavy ray tracing and dense vegetation, and the 5090 is one of the few cards that keeps it above 60 fps at 1440p with ray tracing on.
Expect roughly 240 fps from the RTX 5090 in Atomic Heart at 1440p. With DLSS and Frame Generation available on the 50-series, you can push frametimes even tighter or save power. Pair it with a 4K 240Hz or high-refresh 1440p panel so the 240 fps actually reaches your monitor.
If you game at 1440p and want maximum settings with full ray tracing, the RTX 5090 is the no-compromise choice and is currently stocked at Evetech. That said, an RTX 5080 or RTX 4080 SUPER also clears Atomic Heart comfortably at 1440p for a lot less, so step down a tier unless you specifically want 4K above 120 fps with everything maxed.
To avoid bottlenecking the 5090 in Atomic Heart, pair it with a Ryzen 7 9800X3D or equivalent, 32GB DDR5-6000, a 1000W or larger 80+ Gold PSU and a 4TB Gen4 NVMe SSD. A full RTX 5090 tower lands around R98,000 to R105,000 locally. Skimping on the CPU or power supply is the most common way SA builders waste a card this powerful.
Around 240 fps on high settings at 1440p. Frametimes stay stable, and DLSS can push it higher or lower power draw.
Not necessarily. An RTX 5080 or RTX 4080 SUPER also handles Atomic Heart well at 1440p for noticeably less. Choose the 5090 only if you want the absolute ceiling at 4K with everything maxed.
A Ryzen 7 9800X3D is the strongest pairing and avoids any CPU bottleneck at 1440p. Budget at least a 1000W 80+ Gold PSU and 32GB DDR5 to feed the card properly.
Cap your framerate 3-5 fps below your monitor's refresh in Atomic Heart to keep frametimes flat, and enable DLSS only if you want lower power draw rather than more frames the panel cannot show.
A 650W PSU is a risky ceiling for an RTX 5090 system if you want comfortable safety headroom. SA builders should check total platform draw, PSU age, cable support, case airflow, and upgrade plans before relying on it.
