NVIDIA GeForce RTX 3080 10GB
The NVIDIA GeForce RTX 3080 10GB was a strong gaming card in its generation with 10GB of GDDR6X. In 2026, the 10GB VRAM is limiting for both modern games and AI. For AI, you can run 7B models but anything larger requires heavy quantization. Good used prices, but the 12GB RTX 3060 or used 3090 are usually better AI value picks.
