NVIDIA GeForce RTX 4070 SUPER
The RTX 4070 SUPER is an excellent 1440p gaming card with 12GB of GDDR6X memory. For gaming, it delivers smooth performance at high settings. For AI, the 12GB VRAM limits you to 7B-8B models, which is enough for a personal chatbot or code assistant but not for larger reasoning models. A great choice for gaming-first builds with light AI experimentation.
Full specs →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.
