A 1440p Custom Gaming PC for Gaming and Multitasking
This custom gaming PC Singapore build uses the Radeon RX 9070 XT 16 GB and Ryzen 9 9900X3D for 1440p gaming at $3,915 SGD. The Ryzen 9 9900X3D is AMD's 12-core 3D V-Cache processor with 140 MB of total cache, making it a strong fit for builds where the CPU also runs streaming software, video rendering, or other sustained workloads alongside gaming.
The Phanteks Evolv X2 in black uses a distinctive tri-panel tempered-glass design and supports ATX motherboards with room for large components. Three ARGB fans cover case airflow. The ASUS B650E-E TUF Gaming motherboard adds Wi-Fi 6E and Bluetooth to the build.
The RX 9070 XT 16GB is built on AMD’s RDNA 4 architecture. AMD lists 304W Typical Board Power for the reference specification and a 750W minimum PSU recommendation. This build uses an ASUS Prime AP 750W 80+ Gold PSU.
Storage is a Dynabook AX7300 1 TB Gen 4 NVMe (Non-Volatile Memory Express) SSD as the primary drive, with a Toshiba 4 TB HDD for secondary storage of game libraries, recorded footage, or large working files. The Dynabook AX7300 Gen 4 NVMe SSD provides much higher storage throughput than a SATA SSD, although actual game loading improvements vary by title. RAM is 32 GB of KingBank RGB Soarblade DDR5 at 6400 MHz in the black variant.

PERFORMANCE
Performance at 1440p
The RX 9070 XT averaged 83 FPS in Black Myth: Wukong at 1440p in GamersNexus rasterized testing, with good frame pacing in its 1% and 0.1% low results. Ray-tracing performance varies by game, while AMD FSR 4 upscaling and frame generation can improve output frame rates in supported titles.
In a later 16-game retest reported by TechPowerUp, the RX 9070 XT gained an average of 9% in rasterized performance at 1440p with newer Radeon drivers compared with the review drivers. In that specific test set, it finished ahead of the RTX 5070 Ti. The ASRock card in this build uses the same RDNA 4 GPU and can benefit from those improvements when the relevant Radeon driver is installed.
In Tom’s Hardware’s 1080p gaming suite, the Ryzen 9 9900X3D was 28% faster on average than Intel’s Core Ultra 9 285K. Its 12 cores and 24 threads also make it suitable for mixed workloads such as gaming, streaming and content creation.
The Ryzen 9 9900X3D has a boost clock of up to 5.5 GHz and 140 MB of total cache. Paired with the RX 9070 XT, it provides a strong platform for high-refresh-rate 1440p gaming, although actual performance varies by title, graphics settings and background workload.
The build includes 32 GB of DDR5 memory at 6400 MHz, providing a practical capacity for modern gaming, recording and everyday multitasking.
"These GPUs built on RDNA 4 architecture excel at 1440p and 4K gaming while handling entry-level AI workloads."

Can the RX 9070 XT run games at 1440p?
Yes. In GamersNexus testing, the RX 9070 XT averaged 83 FPS in Black Myth: Wukong at 1440p in rasterized testing, with good frame pacing in its 1% and 0.1% low results. For titles that support AMD FSR 4, upscaling and frame generation can improve output frame rates on top of the native render result. The card’s 16 GB of VRAM also gives useful headroom for 1440p textures.
Why choose the Ryzen 9 9900X3D over the Ryzen 7 9800X3D for gaming?
For pure gaming, the Ryzen 7 9800X3D is usually the more gaming-focused choice. The Ryzen 9 9900X3D is better suited when the same PC also handles streaming, editing, rendering, or heavier background workloads, because it gives you 12 cores and 24 threads instead of 8 cores and 16 threads.
