The Flagship 4K Build
32 GB of GDDR7 on the ASUS ROG Astral RTX 5090, inside a Hyte Y70 White case. This RTX 5090 gaming PC in Singapore pairs NVIDIA's flagship GPU with a Ryzen 7 9800X3D at $11,250 SGD. The Hyte Y70 is a dual-chamber ATX case with a panoramic tempered glass front panel, keeping all wiring behind the motherboard tray and the components fully visible from the front.
The ASUS ROG Astral RTX 5090 runs on NVIDIA's Blackwell architecture with 32 GB of GDDR7 memory across a 512-bit bus, producing 1.79 TB/s of memory bandwidth. That gives the build excellent 4K headroom for modern games, while ray tracing and path tracing performance still depends on the title, settings, and whether DLSS is enabled. The Ryzen 7 9800X3D brings AMD's 3D V-Cache to the AM5 platform: 96 MB of stacked L3 cache that helps keep frame delivery consistent in CPU-sensitive titles at this GPU tier. Cooling is handled by an NZXT RGB Kraken Plus V2 360 mm LCD AIO mounted at the top of the Y70.
The G.Skill Trident Z5 Neo RGB runs at 64 GB DDR5 6000 MHz in dual-channel across the ASUS X870E-E ROG Strix motherboard, which adds Wi-Fi 7 and Bluetooth. Storage is a Samsung 990 Pro 4 TB Gen 4 SSD. The Seasonic Vertex PX 1200W 80+ Platinum power supply covers the RTX 5090's high power requirement with room for the rest of the system.

PERFORMANCE
Performance at 4K
At native 4K without upscaling, the RTX 5090 32 GB delivers excellent raster gaming performance in demanding modern titles. GamersNexus recorded 95 FPS average in Cyberpunk 2077: Phantom Liberty at 4K Ultra with no ray tracing and no upscaling, a 50% lift over the RTX 4090's 64 FPS average in the same test.
Across its full 4K Ultra rasterization suite, Tom's Hardware found the RTX 5090 25% faster than the RTX 4090, with individual games ranging from 6% to 43% ahead. In Black Myth: Wukong with full ray tracing at 4K using quality mode upscaling, Tom's Hardware recorded 62 FPS on the RTX 5090 versus 48 FPS on the RTX 4090. With DLSS 4 and Multi-Frame Generation enabled in supported games, displayed frame rates can go much higher, but base rendered FPS and input latency still determine how responsive the game feels.
The Ryzen 7 9800X3D's 3D V-Cache helps keep frame delivery consistent in CPU-sensitive games. In lighter esports titles and simulation-style games, the 9800X3D's 96 MB of stacked L3 cache can help reduce frame-time spikes at this GPU tier. The 64 GB of DDR5 6000 MHz RAM also gives the build room for content creation and video editing alongside gaming without requiring a memory upgrade.
"For gaming, anyone who isn’t playing on 4K or higher resolutions won’t get as much relative gain out of this card."

FAQ
Frequently Asked Questions
How much does an RTX 5090 gaming PC cost in Singapore?
An RTX 5090 gaming PC in Singapore costs $10,000 to $14,000 SGD depending on the CPU, RAM, storage, case, and cooler tier. This build with the ASUS ROG Astral RTX 5090, Ryzen 7 9800X3D, 64 GB DDR5, and 4 TB storage comes to $11,250 SGD. If the RTX 5090 is the priority and other specs can be scaled back, a smaller storage drive or different case configuration can reduce the total price.
Can this PC run 4K games with ray tracing?
Yes, this build is designed for high-end 4K gaming, including ray tracing in many modern titles. However, exact FPS depends heavily on the game, ray tracing mode, and whether DLSS is enabled. GamersNexus recorded 95 FPS in Cyberpunk 2077: Phantom Liberty at 4K with no upscaling and no ray tracing. In Black Myth: Wukong with full ray tracing at 4K using quality mode upscaling, Tom's Hardware measured 62 FPS on the RTX 5090. With DLSS 4 and Multi-Frame Generation enabled in supported games, displayed frame rates can go much higher, though base rendered FPS and input latency still matter.
Why does this build use 64 GB of RAM?
At this GPU tier, 64 GB of DDR5 covers gaming alongside content creation tasks without a memory ceiling. Modern AAA games can use a large amount of system RAM once browsers, launchers, Discord, OBS, and background apps are open. With 64 GB, you can run a game, record or stream, and keep work apps open without the system paging heavily to storage. For a pure gaming build, 32 GB is still practical, but 64 GB gives this flagship build more room for video editing and 3D work.
