A r/LocalLLaMA user (385 upvotes, 63 comments) purchased a Chinese-modified RTX 4080 with 32GB GDDR6X — double the official 16GB — for around €1,300. These mass-produced modified cards from companies like 'CT AI' use custom PCBs with memory on both sides. At 32GB, they can run Qwen3.5 27B and similar 30B+ models that choke on standard 16GB cards, making them a cost-effective alternative to professional GPUs for local inference.
