Quick Answer
At 1080p the RTX 5090 runs NBA 2K25 at roughly 220-280 fps on max settings. That is comfortable headroom for a fast 1080p panel running 240Hz or higher, and NBA 2K25 is a high-fidelity sports sim that looks best at locked, high refresh. Expect the card to sit well within its limits at this resolution rather than being pushed hard.
What to expect from the RTX 5090 at 1080p
NBA 2K25 on the RTX 5090 lands around 220-280 fps at 1080p on the highest preset. NBA 2K25 is a high-fidelity sports sim that looks best at locked, high refresh. To turn that into a genuinely smooth session you want a fast 1080p panel running 240Hz or higher; a slower panel hides most of the card's output. A Ryzen 7 9800X3D or Core Ultra 7 keeps the 1% lows healthy so the average never feels choppy.
The build that does NBA 2K25 justice
At R60,000-plus locally, an RTX 5090 only makes sense in a balanced rig. A quality 1000W power supply such as a Corsair RM1000e or MSI MAG A1000GL from around R2,800 gives the RTX 5090 the transient headroom it needs. Use 32GB of DDR5-6000, a fast NVMe SSD so asset streaming never stutters, and a case with real airflow because the card draws up to 575W under load. Behind a fast 1080p panel running 240Hz or higher, that platform shows NBA 2K25 exactly as the developers intended. Evetech ships these assembled, stress-tested and locally warrantied, which is what you want at this tier.
FAQ
What frame rate does NBA 2K25 hit on the RTX 5090 at 1080p?
Around 220-280 fps on max settings. A strong X3D CPU keeps the lows steady.
Do I need anything besides the GPU to see those frames?
Yes. Pair the card with a fast 1080p panel running 240Hz or higher and a Ryzen 7 9800X3D-class CPU. Without the right screen and processor the RTX 5090 is held back by the rest of the build.
Is the RTX 5090 overkill for NBA 2K25 at 1080p?
It carries clear headroom here, so it is more future-proofing than a strict requirement. A 5070 Ti or RX 9070 XT is the value alternative.
Size the whole rig, not just the GPU.
For NBA 2K25 at 1080p, run the RTX 5090 with a fast 1080p panel running 240Hz or higher and a Ryzen 7 9800X3D so nothing throttles the frames. Compare fully built, locally warrantied RTX 5090 systems at Evetech.
