I have a used 7970. I run it stock, except that I have tested with MSI AB to 7970, while verifying no artifacting with MSI Kombuster. I've put a few dozen gaming hours on it, and have used AB fan profile to keep temps below 70c (most games) or 75/76 max for stressful games (Crysis 2 hi def dx11). It has been in an FT02, so temps have been easy to keep down. I'm offering it for $375, plus $10 shipping. Let me know if you are interested.
