Local AI fit: 32B-class models. Rule of thumb for 4-bit quantized models; context length and other apps eat into the same memory.
Why you buy it
- 24GB with full CUDA support
- Still second only to the 5090 in games
- Holds value if you resell later
Why you hesitate
- Used prices stay close to what it cost new
- 450W plus the 12VHPWR connector deserves inspection
- No warranty on most listings
The editor's take
Discontinued, yet used prices barely fell, because AI demand for 24GB CUDA cards did not. It still beats everything except the 5090 in games and runs 32B-class models comfortably. Buy from listings with the original box and a return window; mining-era paranoia does not apply here, but AI-farm duty does. Check the power connector's condition, this generation's known weak point.
Who it's for: Local AI builders and 4K gamers hunting the used market for 24GB of CUDA without paying 5090 money.
