PERFORMANCE
Performance at 4K
The RTX 5080 16 GB ran Resident Evil 4 at 122 FPS and FFXIV Dawntrail at 112 FPS at 4K, both tested by GamersNexus. Dragon's Dogma 2 reached 84 FPS, Dying Light 2 reached 81 FPS, and Starfield ran at 76 FPS at the same resolution.
The card carries 16 GB of GDDR7 VRAM and a 360 W TGP (Total Graphics Power), fed by the Asus ROG Strix 1000 W PSU. The Intel Core Ultra 9 285K is a 24-core LGA1851 processor on the Z890 platform, covering game workloads alongside recording, rendering, and content creation tasks. The 64 GB of DDR5 at 6000 MHz supports those combined workloads without constraint.
Cyberpunk 2077 shows the potential for this tech, with the RTX 5080 able to max out the game at 4K while averaging 128fps.

FAQ
Frequently Asked Questions
How much does an RTX 5080 gaming PC cost in Singapore?
This RTX 5080 gaming PC in Singapore is priced at $5,000 SGD. It includes the Intel Core Ultra 9 285K, Nvidia RTX 5080 16 GB, 64 GB DDR5 RAM, 1 TB PCIe Gen 5 NVMe SSD, a 240mm AIO cooler, and Activated Windows 11 Home, all in the Asus A31 case. Mansa Computers also builds RTX 5080 configurations from $5,350 SGD in different cases and platforms.
Can the RTX 5080 run games at 4K?
Yes. In GamersNexus testing at 4K, the RTX 5080 reached 122 FPS in Resident Evil 4, 112 FPS in FFXIV Dawntrail, 84 FPS in Dragon's Dogma 2, and 76 FPS in Starfield. DLSS 4 Multi Frame Generation can display higher frame rates in supported titles, but it should be treated separately from the native 4K benchmark numbers above because it generates additional frames.
What is the Samsung 9100 Pro Gen 5 NVMe and is it worth it?
The Samsung 9100 Pro is a PCIe 5.0 NVMe SSD with sequential read speeds up to 14,700 MB/s, roughly double the throughput of a PCIe Gen 4 drive. The Z890 platform in this build includes a Gen 5 M.2 slot that runs the drive at full speed. For gaming load times, the difference over Gen 4 is modest. For large file transfers, video project imports, and content creation workflows, the Gen 5 drive moves data in half the time of a Gen 4 equivalent.
