A 4K Gaming PC in Singapore Built Around the RTX 5080
This RTX 5080 gaming PC in Singapore uses the Gigabyte RTX 5080 16 GB and Intel Core Ultra 9 285K inside a Lian Li PC-O11 Evo XL Dynamic. It is built for customers who want a high-end desktop for 4K gaming, multitasking, and production work in one clean black showcase build. Total price: $8,400 SGD.
The Intel Core Ultra 9 285K is a 24-core Arrow Lake processor with 8 Performance cores and 16 Efficient cores, giving the system strong headroom for gaming, rendering, encoding, and background tasks. The 64 GB DDR5 kit at 6000 MHz also gives the build enough memory capacity for heavier workloads beyond gaming.
Storage is a dual-drive setup: a 1 TB KingBank Soarblade for Windows and frequently played games, plus a 4 TB Samsung 990 Pro NVMe SSD for larger game libraries and production files. The Lian Li Uni Fan setup and TRYX ARGB Panorama 360 AIO keep the cooling and lighting matched across the build. Windows 11 Pro is included.

PERFORMANCE
Performance at 4K
GamersNexus measured the RTX 5080 at 112 FPS in Final Fantasy XIV at 4K, where it was about 15% faster than the RTX 4080 and RTX 4080 Super in that benchmark. Tom's Hardware found the RTX 5080 was 9% faster than the RTX 4080 Super in Tom's Hardware 4K Ultra gaming results overall, with a stronger 23% uplift in Warhammer 40,000: Space Marine 2 at 4K, which Tom’s Hardware linked to the GDDR7 memory bandwidth upgrade.
With NVIDIA DLSS 4 and Multi-Frame Generation enabled in supported titles, displayed frame rates can increase further. Multi-Frame Generation inserts AI-generated frames between rendered frames, so it should be treated separately from native benchmark performance. The native 4K numbers above are the baseline.
The Intel Core Ultra 9 285K features 24 cores (8 Performance cores and 16 Efficient cores) on Intel's Z890 platform. In gaming, the Performance cores handle the main game workload while the Efficient cores help with background tasks. In production work, all 24 cores are available for rendering, encoding, and simulation.
"NVIDIA recommends the RTX 5080 for maxed out gaming at 4K Ultra HD."

FAQ
Frequently Asked Questions
How much does an RTX 5080 gaming PC cost in Singapore?
This RTX 5080 gaming PC in Singapore costs $8,400 SGD at Mansa Computers. That includes the Gigabyte RTX 5080 16 GB, Intel Core Ultra 9 285K, 64 GB DDR5, dual NVMe storage (1 TB + 4 TB), Seasonic 1000 W PSU, and Windows 11 Pro. Pricing varies with component market costs.
Can the RTX 5080 run games at 4K?
Yes. GamersNexus recorded 112 FPS in Final Fantasy XIV at 4K, and Tom's Hardware measured a 4K suite average of 133.9 FPS. In very demanding titles, native 4K performance will vary depending on the game, settings, and whether upscaling is enabled. With DLSS 4 and Multi-Frame Generation enabled, supported titles can show higher displayed frame rates at 4K, depending on the game and settings.
Why does this build use Windows 11 Pro instead of Home?
Windows 11 Pro adds BitLocker encryption, Remote Desktop, Hyper-V virtualisation, and advanced management tools not in Home. For a build of this spec, Windows 11 Pro is useful if you also use the machine for professional work, remote access, or running virtual machines alongside gaming.
