A Full ATX Gaming PC, Built in White
This ATX gaming PC in Singapore runs an XFX Radeon RX 9070 XT 16 GB with a Ryzen 7 7800X3D, 64 GB of DDR5 6400 MHz RAM, and 4 TB Gen 4 NVMe SSD storage, priced at $4,265 SGD. The build targets 4K gaming in a full-size ATX white enclosure, available from the Mansa standard ATX line.
The 4 TB Lexar NM790 Gen 4 SSD gives enough space for a large modern game library without constantly uninstalling titles. Many modern AAA releases run between 50 GB and 150 GB each, so at 4 TB you keep 30 to 40 large titles installed at once. At 64 GB of DDR5 6400 MHz, the system runs gaming, OBS for game capture, video editing, and background apps without running out of memory.
The NZXT H3 Flow white case uses three white case fans and a Thermalright Peerless Assassin 120 ARGB cooler in white. The Klevv Cras V RGB DDR5 sticks in white carry the colour theme all the way to the RAM slots. Mesh panels across the front and top of the H3 Flow help maintain airflow during long gaming sessions. The Asus B850-G Gaming Wi-Fi 7 board brings Wi-Fi 7, Bluetooth, and PCIe 5.0 on the AM5 platform, and the Asus TUF EVO 850 W 80+ Gold PSU provides additional headroom above AMD's recommended PSU requirement for the RX 9070 XT.

PERFORMANCE
Performance at 4K
The RX 9070 XT runs Cyberpunk 2077 at 53 FPS at 4K, Resident Evil 4 at 103 FPS at 4K, and Starfield at 70 FPS at 4K, based on benchmark testing from GamersNexus. The RX 9070 XT targets high-refresh-rate 1440p gaming comfortably while still handling many modern games at 4K with reduced settings or upscaling enabled. The RX 9070 XT runs on AMD's RDNA 4 architecture, built on TSMC's 4 nm process, with 16 GB of GDDR6 VRAM and a 304 W TBP (Total Board Power). The 16 GB VRAM gives more headroom for texture-heavy 4K titles at higher settings. For games needing an extra FPS boost, AMD FSR 4.0 upscaling is supported in compatible games.
The Ryzen 7 7800X3D uses 3D V-Cache to improve frame pacing in CPU-sensitive games. Total War: Warhammer 3, Baldur's Gate 3, and large open-world titles run smoothly on the 7800X3D. With 64 GB of DDR5 6400 MHz, streaming via OBS runs alongside the game without heavily impacting gameplay performance. The 7800X3D sits on the AM5 platform using the same AM5 socket as newer Ryzen processors like the Ryzen 7 9800X3D for a future CPU upgrade path.
The Ryzen 7 7800X3D's low power consumption and class-leading game performance make it an ideal choice for anyone considering a new PC gaming rig.
