AMD Radeon RX 7800 XT
$430$499 MSRP
The AMD Radeon RX 7800 XT is one of the best 1440p gaming GPUs available, offering 16GB of GDDR6 at a competitive price. It has excellent Linux driver support through Mesa/RADV, making it popular with Linux gamers. However, like all AMD consumer GPUs, it lacks CUDA support and is not recommended for AI workloads.
Best For1440p gaming, especially on Linux
VerdictThe 1440p king on a budget — great Linux support, no AI use.
