Duittuit,
Both mine came already overclocked - I've tweaked Hollywood's up a little more, but the one in Kitt keeps wanting to drop back into 2D so it's running just as it came out of the box.
Hollywood is running a Galaxy - drawback was I had to replace the power supply - it takes an 8-pin plus a 6-pin to power it.
Kitt is running an MSI - not real impressed with it most the time due to what I mentioned above with the 2-D. MSI said to try it in a known good computer - as in try it in Hollywood and if it still does that, there might be an issue with the card.
