9800X3D and RX 9070 XT in the NZXT H6 Flow
This AMD gaming PC build in Singapore runs a Ryzen 7 9800X3D and ASRock RX 9070 XT 16 GB inside the NZXT H6 Flow Black, priced at $3,960 SGD and built by Mansa Computers. The H6 Flow is a dual-chamber mid-tower with mesh panels on both the front and top, a layout that channels fresh air directly to the GPU and CPU without obstruction from the PSU or storage bays.
The AMD Ryzen 7 9800X3D is an 8-core Zen 5 AM5 processor with 3D V-Cache, a stacked cache design that adds 96 MB of L3 cache on top of the standard die to reduce latency in cache-sensitive game workloads. The 9800X3D is one of AMD’s strongest gaming CPUs across a broad range of titles. The Asus X870E Plus TUF Gaming Wi-Fi 7 motherboard adds Wi-Fi 7 and Bluetooth, and the Thermalright Peerless Assassin 120 Black air cooler keeps the processor at low temperatures in the H6 Flow's open airflow path.
Memory is 64 GB of KingBank Soarblade RGB DDR5 at 6400 MHz. Storage is a Samsung 990 Pro 2 TB NVMe (Non-Volatile Memory Express) Gen 4 SSD. Power comes from a Thermalright 850 W 80+ Gold PSU, housed in the H6 Flow's separate lower chamber so it draws its own cool air from the bottom intake.

PERFORMANCE
Performance at 4K
The RX 9070 XT is a 4K GPU. In Resident Evil 4 at 4K, it scores 103 FPS. Starfield runs at 70 FPS, Dragon's Dogma 2 at 70 FPS, and Dying Light 2 at 62 FPS, based on GamersNexus benchmark testing at 4K.
The card draws 304 W TBP (Total Board Power) under gaming load. The Thermalright 850 W PSU runs below capacity at that draw, and the H6 Flow's front mesh intake feeds cool air to the GPU chamber without restriction. AMD FidelityFX Super Resolution 4 (FSR 4) is available in supported titles and raises frame counts above the native figures listed above.
The Ryzen 7 9800X3D's 3D V-Cache keeps latency low in cache-sensitive game workloads. At 4K, the GPU is the primary bottleneck in every tested title, and the 9800X3D does not limit the RX 9070 XT's output in any benchmark.
"The AMD Radeon RX 9070 XT provides strong mainstream performance at a great price. The RDNA 4 architecture delivers significant generational improvements in AI and ray tracing performance"

FAQ
Frequently Asked Questions
What is the NZXT H6 Flow and why is it good for gaming PCs?
The NZXT H6 Flow is a dual-chamber mid-tower case. The main chamber holds the motherboard, GPU, and CPU cooler, while the lower chamber houses the PSU and storage. This separation allows each section to draw its own airflow. The front and top panels are mesh, bringing fresh air directly to the GPU and CPU without passing through the PSU compartment. For higher-power GPUs like the RX 9070 XT, this clean airflow path helps keep temperatures low.
Can this PC run 4K games?
Yes. The ASRock RX 9070 XT 16 GB scores 103 FPS in Resident Evil 4 at 4K and 70 FPS in Starfield at the same resolution, based on GamersNexus testing. Many current titles at 4K high settings run above 60 FPS. With AMD FSR 4 enabled in supported games, frame rates can go higher.
What is the Ryzen 7 9800X3D?
The Ryzen 7 9800X3D is one of AMD’s top gaming processors. It is an 8-core Zen 5 AM5 chip with 3D V-Cache, adding 96 MB of L3 cache to reduce latency in games. It ranks among the best-performing gaming CPUs across many tested titles. At 4K, the GPU is usually the limiting factor, and the 9800X3D is unlikely to meaningfully limit the RX 9070 XT in most games.
Is 64 GB of RAM too much for gaming?
Most games use 16 GB to 32 GB of system RAM at most. The 64 GB kit in this build covers gaming and leaves room for video editing, streaming, virtual machines, or many browser tabs running at the same time. The KingBank Soarblade DDR5 kit runs at 6400 MHz, toward the higher end of DDR5 speeds on the AM5 platform.
How much does an AMD gaming PC cost in Singapore?
An AMD gaming PC in Singapore typically ranges from around $2,800 SGD for entry-level builds to $5,000 SGD and above for higher-end configurations. This build with the Ryzen 7 9800X3D and RX 9070 XT in the NZXT H6 Flow Black is priced at $3,960 SGD. Builds with a lower-tier GPU or less RAM will cost less.
