What Buyers Say
QTHREE Radeon RX 550 4GB GDDR5
72 out of 100 medium confidence 12 reviews
This budget-friendly graphics card is a great fit for upgrading older small form factor PCs, with several verified 5-star reviews praising its multi-monitor support and plug-and-play ease on Linux. However, a few serious issues stand out: one verified buyer got repeated blue-screen lockups, the fan speed sensor is non-functional on another unit, and the lack of a driver disc forces users to hunt down updates online. Overall, it is a capable low-end card for light gaming and office work, but reliability and support documentation are hit-or-miss.

- Plays Minecraft and Roblox smoothly on i5-8500
- Easy plug-and-play installation on Linux
