Well got it all working, but blimey the card runs hot, the back (ie the bit without the fan) of the card is unpleasant to touch, I'm putting it down to the room heater of the CPU cooler sitting under the graphics card and the heat rising into the card. I've not even 'Overclocked' the card to the correct speed either.

I can't under stand how a single core 1.5mHz macMIni can run so cool, but a dual 1.42 with a heatsink larger than the whole MacMini runs like a 1 bar electric heater.

without the 3d graphics drivers it really doesn't like Lucy!
