What Buyers Say
Sapphire Radeon RX 7900 XTX PULSE 24GB GDDR6 Black
The Sapphire Pulse RX 7900 XTX is widely praised for its excellent price-to-performance ratio, offering massive 24GB VRAM and strong rasterization that rivals the RTX 4080 at a much lower cost. Users highlight its cool and quiet operation, though some note it runs hot in cases with poor airflow and requires a high-wattage PSU (800W minimum, 1000W recommended). A few negative reviews mention receiving a wrong item (keyboard instead of GPU) or driver issues that were resolved by upgrading other PC components. Overall, it's considered a beast for gaming and 3D work, but not ideal for eGPU setups.
