Oh i know you weren't . Its my personal annoyance now as I am pretty sure it is the component which is holding my system back but 1) its always something and 2) graphics cards are ridiculous amounts of money so I say oc it as far as safely possible. However I do take your point that at the minute that is without cause, can't wait for bioshock though to see if it can strain the card.
I just downloaded the demo on XBl and its not that amazing tbh.. i was hoping for much more.. the graphics are incredible tho.. .. im waiting for crysis and stranglehold.. stranglehold for the XBox 360 tho
