I just bought a 9600GSO 512MB 128-bit and overclocked it with ntune from default to great config.It equals a HD 4670 in config but can give more than that in performance.Watch this pic.I can even OC to 1100/1320MHZ .
Eventhough OC it still idles at 51-53 degress and on load goes to 65-66 degrees MAX.
Great card from PALIT.

now I have overclocked to 750/1000
see this now and comment upon it.
