Guys, please see:

It seems the res/colour-depth is associated from my tests. As for the "not enough power", it has to be an erroneous message coz I've tried with all fans, both CD's and the floppy disconnected and I have a 450w Enermax PSU.
Quite frankly I think NVidia are bang out of order releasing £400 hardware in this state. That £400 entitles the purchaser to the very best quality, not some shonky cash-in piece of second-rate crap which is what these supposedly 'uber' cards actually are. I think it's time NVidia got a wake-up call by way of law-suits and bancruptcy. Very angry here.
