NVIDIA RTX 3080 10GB
The RTX 3080 10GB is the original flagship-killer from NVIDIA's Ampere generation. With 10 GB of GDDR6X at 760 GB/s and used prices around $350-400, it offers incredible memory bandwidth for 7B model inference. The 10 GB VRAM limit means larger models won't fit, but for its primary use case of fast 7B inference, it still holds up well.
